Right now I am having that problem that all artist gets... self-confidence issues. Recently I have thrown away 4 animation projects in 3 weeks. That always happens to me, I get excited about a project, then about halfway through I think it's awful or get bored with it and then toss it. I'm taking a break now to clear my head, and I'm hoping that I can get through the next project that I have in mind now. That was just a nice way to vent.
P.S. Who else thinks that Disney should make the next tinker bell movie about tink meeting peter pan?
