It's tough critiquing your own work sometimes, but we all do it. =/

Little over a decade ago, I wold get so frustrated that what I had sketched was bad that I would rip the paper out of the pad, crumple it up and throw it across the room.

Yet I persisted and now look at me. Even though I am 100's of times better than I was in the late 90's and early 2000's, I'm still a bit harsh on my own work. Though, in the last few years, I've been really happy with how stuff turned out.

What helps is the drive to reach a level where you look at it and say, "Now, I have arrived!!!"

We're our own worst critics.
