I turned in the last page of Spotlight: Prowl last night.
The entire issue was drawn digitally in MangaStudio 4.0 EX. I haven't done anything Transformers in this software until now. I've always thought drawing something as mechanical as Transformers digitally would be kind of difficult because of the more precision lines that they required, but it wasn't as difficult as I had imagined.
I've always wanted to try more industrialized look on Transformers. Something along the line of stuff you may see in Steel Battalion. Military looking and leaner alien robots rather than more human-like. I tried some Prowl design that never made it into the book. Looking back, I may not even go for it myself.
Oh well, going back to the drawing board. :p
