[PORTRAIT CHALLENGE] Masterclass Lesson #2: Sketching Your Portrait for a Firm Foundation

Masterclass Lesson #2 for the Acrylic Portrait Painting Challenge is open!

In this lesson, you will learn how to draw an accurate sketch that will help keep you from getting frustrated while painting. You will also be set up to create a portrait with realistic proportions, and a true likeness—where it really looks like the person you’re trying to paint.

That’s the kind of portrait you’ll be proud to show, sell, or give as an exquisite gift!

Just as a contractor wouldn’t build a house without a proper foundation, you shouldn’t paint a portrait without one either. A rock-solid sketch is the best way to establish a firm foundation for the rest of your portrait to be built upon. Take your time to do it right, and you will set yourself up for success, and avoid a lot of potential hassle later.

Sketching as a firm foundation for your portrait.

In our previous step, I showed you how to prepare your canvas for the sketch by creating a well-formed grid.

If you followed my instruction, you will have sealed that grid with first a layer of matte medium. Then you followed up with a roughly 50%/50% mixture of acrylic matte medium and white acrylic gesso, and let it dry for at least a couple of hours.

Now, you have a canvas that is ready to sketch upon. The matte medium/ gesso layer provides not only a barrier to the grid so you can’t erase it while sketching, but it also gives the canvas the perfect texture to sketch with a colored pencil. Back in 2017, I discovered that colored pencil erases like a dream on a properly prepared canvas. And you can seal it in without minimal loss of detail to your sketch.

Try it, and you’ll find out how fun it can be to sketch on your canvas. 🙂 You’ll never want to go back to graphite pencil again!

Another benefit: you can pick any colored pencil hue you want to match the skin tone of the subject. Remember, with my glazing technique, you will be able to see through the paint layers, down to the colored pencil until you have enough layers to cover it up. And in a few areas, even when your painting is finished, the colored pencil will shine through a bit. So pick a brown color that works best for you. Sepia, Chocolate, brown ochre, and terra cotta are all good colors for sketching.

Here’s the steps to creating a masterful sketch, a firm foundation for your painting.

  1. Set up your tablet (Kindle, iPad, etc) or printed reference photo next to your canvas, and display the gridded reference photo. Need something to hold your tablet up? My free course shows you how to make your own Reference Photo Holder) The reference photo is your blueprint to paint a portrait from your photo. It’s what your finished painting should look like. 
  2. Sketch the outline first. Pay attention to where you are placing your lines. Try to see the grid squares as fractions. (“the line will intersect here at 1/4 of the way up, or 1/2 of the way over, etc”
  3. Fill in the features, loosely: eyes, nose, mouth, etc. The eyes are the most important feature, so really make sure you capture the shapes of not only the eyes, but the eyelids and eyebrows.
  4. Delineate the tonal values. Shade in the areas that are darker, and pay attention to exact forms that the shadows create. Try to think of them as abstract shapes like stretched out triangles, oblong ovals, squished rectangles, for example. As you fill in these values, the planes of the face will start to emerge. You will create a convincing sense of three-dimensional form.
  5. Refine your sketch and add any missing detail. Step back a bit and make sure you have the proportions correct. The grid will have done the “heavy lifting” for you, by keeping your lines pretty accurate. But you might need to erase and redraw some of the features for greater accuracy. Finish up with the wrinkles in the clothing and on the hat, if needed.

Watch my in-depth Masterclass acrylic online tutorial below to see these steps in action.

After learning from this video, You’ll know exactly how to do it.

Before you watch, I want you to know that this lesson is VERY in depth. It’s one hour long! But please, make the investment in your art talent, grab a cup of coffee or tea, and watch the whole thing. If you do, I promise that you will have greater clarity on how to begin an acrylic portrait from here on out.  Every portrait you do will be that much better.

Here’s the video…

Is it done?

How accurate does it need to be? You only need to have a likeness 90% of the way there to have a fantastic sketch.

It doesn’t have to be perfect. The painted layers will dial in the likeness the rest of the way. You don’t need to make this sketch into a drawing. Meaning, you don’t need to shade in everything to the point that it looks like a finished drawing that you could hang on your wall.

No.

The sketch is for YOUR  benefit…and also that of the portrait!

It doesn’t have to amaze others at this stage. It just needs to be accurate. It needs to describe the form, the contours, the three-dimensionality of the subject with line and value. You simply need to make yourself a guide so you know where to place your glazes when you segue into the painting process.

Now the painting, when it is finished, let THAT amaze others! (and you 🙂 )

There you have it! Now you know exactly how to create a great sketch for your portrait, a firm foundation you can build the rest of your portrait upon. The next step is to seal in your sketch and ease your portrait into a painting with the first few glazes.

I’ll see you in our next class! Until then have a blessed day and use that talent God gave you to its fullest!

Yours for Better Portraits,
