The pointpusher from Dreamworks works like a dream, oh god that was terrible..His workflow videos are pretty rad and hes a pretty stand up cool guy with all his walkthrough videos on his work process. His work is pretty rad. I like watching his paintings get better and better as times goes on and seeing how he does it.
I should post a video but almost decided against it based on the fact he has a lot of photoshop maya and different tutorials and workflow time laps things its impossible to decided which ones to show.. but i found this one interesting.
