One of the the worst things that I do to myself, is that if I don't complete, or at least approve of something I've put down in an appropriate short period of time, I begin to believe that I don't have what it takes to be an artist. This is one of those raw and very tender aspects of myself that I do. Not. Like. We all have our issues (right? 0.0). I tend to be on the side of can't get out of my head... What's the actual expression?? Letting my thoughts get ahead of my actions, or messing up things (in everyday life as well) because I'm thinking about it too much.
That said, I've always never really wanted to draw out aging, because I could never get it right it seemed. But spending a couple of hours on Monday, glued to my chair, and many attempts later, I got this woman. And she isn't perfect (I'm still convinced the eyes need more work), but I'm a semi perfectionist, so putting this up doesn't absolutely freak me out.
Learn from mistakes, get feedback, don't trash anything you draw. How else will we learn?
