The colors are pretty nice:) I don' t like the smudgin though, it just seems to big in terms of the brushes you used and not crisp enough. And I think the right side may be a little TOO dark.
edit: idk if I said it yet, but if I didn' t: Welcome back:)
Yeah I didn't really like the smudging at all, so I tried hiding some of it with lighting/c4d effects, but yeah the right side is pretty dark. And thanks for the welcome back
