Admission: I'm lost as to how to colour this with a red tint and not make it ugly.

Blame a lack of experience and over-comfort with blue tints. I'd would sincerely appreciate an edit, if anyone's willing. Lame, I know, but I've been screwing with it since Stephen suggested unification way back there, and I've come up with nothing. I do kinda like it as is, but obviously I haven't seen the alternative done properly yet.
Edit:I think I like it now because the sky/ground compliment eachother quite nicely, imo. The red/orange sky over the grren/blue earth. I know it's unrealistic, though, and I could be way off, but my brain twitched and I thought I'd voice it.
