Saw a break sketch of robaato's on twitter today. So I copied it to see if I could. That kind of stuff can effect me you know? You see something, and you start to question how you work and how much you can get done.
I did mine in 15 minutes, I'm assuming his too longer to add some effects and polish; to me, this is what a sketch should be in the truest sense.
I'm learning I spent a lot more time in thumb nailing than I maybe should; it's best to just get something on paper and go from there, you know?
