The same here, I could not resist to try out that week his technique of visualizing through darkness. Because a year back I left unfinished some light beings concepts, unsatisfied with my technique. I started Photoshop a year back. I almost lost hope to finish those black and white concepts when here came the life saving Bobby's lesson 1! And very easy in 2 days during the lesson I did a new one from linework to final finish. It is too dark, but at least I could visualize it so much easier and faster! The character in the center is after the lesson, the 2 at the sides are before it.
I also ned to say I really like what you guys do at the caricature class! Very curious to see more.
