Something I did long ago. Pixel practice in revamping sprites.
First made the high color count one, then downgraded it to use the same colors as the 8-bit sprite. Made the pants into some sort of futuristic vest that merges boots and pants, and the gun is something of like an automatic rifle of the future.
Also, I can't help thinking that every time I post something I did on this thread I'm derailing it because "This is a Castlevania forum, thus this thread must go for Castlevania sprites"... Would it be better if we had a "Pixel Art Showcase" thread?
