Toni, what the hell is Haggar doing in your last 2 screenshots? It looks like he's dancing or something
I prefer Nobody's pallete, though it's hard to be sure without looking at some enemies too. But Toni's work is pretty good too.
Edit: And I could do it with Nobody's pallete an no copper effect at all, just plain blue at the sky. It would be no problem IMO if using the copper there would lead to any problems. Dunno if using that copper effect is any easy with Blitz Basic.
