EYE - PASTEL |
Blending is the trick from what I've learned. Mixing and blending the right ones will give you any color imaginable. The other trick I found out about was to back away from the work often and look at it from a different distance and angle.
When drawing my eye (which I hope to try again), I was looking into a mirror attached to my easel. The drawing is on a 24 x 36 piece of paper, so you can imagine how large the eye had to be. Looking at it up close for too long will distort the image, so backing up is a good idea.
