As you finish your animals, you can begin your final layer masking practice by having a buddy take your picture of you holding a paintbrush.

We will use layer masking to create the illusion of you painting color on yourself.

1. Import your photo into Photoshop. Fix the levels and boost the saturation a tiny bit.

2. Duplicate the layer by clicking CTRL+J.

3. Turn the layer you just duplicated to black and white by clicking Image--> Adjustments--> Black and white

4. Put a Layer Mask on your black and white layer.

5. Make sure your MASK is selected. Click your brush tool. Find a brush with a paintbrush type texture in your brush menu. 

6. Use black paint to "hide" parts of your black and white image, showing color below.

7. Now make sure your black and white image thumbnail is selected (Not the mask). Using a LARGE, soft-edged brush, click the burn tool and softly burn the edges of your image, creating a vignette look like the photo above.
