After a feedback session with a friend (thanks Vlad for paintovers!) I believe I have improved on the concept of this piece. Unfortunately the original high res working file was lost, so the most I can do with this one anymore is color adjustment. Re-rendering lost quality isn't in the list of my favourite things to, and I believe I have learned what I came for.
Ultimately it's my best piece yet and I am very pleased! Tried to snap as many WIP screens as I could along the way, too.
