I tend to like the crop of just my eyes and nose the best, as those are the features that I think I've captured most accurately. I know that a lot of people have difficulties with eyes, but for me, that's the one feature that I'm able to capture every time. The mouth is a different story- and the hair- those two things stump me every single time!
It's been fun hearing from those of you who share some of my bizarre traits (from the last post). I have a feeling that maybe a lot of us artists are probably more similar than we realize, personality-wise. Especially regarding the shyness. Isn't it interesting that a lot of us are shy, yet we choose to be so "assertive" with our artwork?
