In the process of working on the character turnarounds for Obscurum, my shortfilm. I will soon move over to doing color/line tests in some of the different software as I'm not 100% sure which one to use. At the moment I know I will try to do some of the post-production in After Effects.
Animating-wise I'm leaning towards Flash (Frame by Frame, no tweens), as I know that program inside and out. TvPaint is also an option, but I just started using it and I'm still figuring the program out. I'm kinda warming up to it too though.
