It's not an art block, it's an art cramp. Which is just slightly different.

For me, it' when you get addicted to your own art, and draw good stuff that all looks pretty much the same. It occurs because your brain's wiring isn't quite in the right balance between dealing with life and correctly processing artistic thought.

I need to fix it.
Badly.

So instead of trying to come up with half assed ideas that only entertain me for a short while. I'm actually going to try drawing something that is artistic, not just carbonated candy pop pinup girls on white backgrounds.

Wish me luck.
