I had such a blast with that last 30min sketch that I decided to jump back in with Batman.
The image in my head was slightly different than the finished product here but I'm totally cool with that. To be honest, the image in my head was slightly beyond my ability. It was super valuable for me to realize that I couldn't quite do it and also why I couldn't do it.
In this case my knowledge ended just shy of the image in my head but that experience tells me point blank what I need to work on. In the end I knocked a decent little sketch and I learned a little about my current limitations.
All is well in Gotham!
