Hello everybody! Thanks a lot for all the input!
and sorry for my late response!
@Ambivorous: I intend to keep the rock spherical indeed as that was part of my initial concept of these floating island planets!
I see the sense in having the clouds frame the picture, but I don't really want to make everything spherical in that way. I'll try to think about how I arrange the clouds though!
@EvilEye: all fair points that I agree with! I'm actually unsure whether to even include the blue afterglow in the first place I don't think the piece really needs it. It sort of works against the simplicity, or maybe it could be done in a more delicate manner.
@Drazelic: also a fair point! And why I in my initial post said I was the most unsure about the leaves. I have a few different styles of rendering going on there at the moment and I'm not really a fan of either. What I'm aiming for is something light and cartoonish while still maintaining detail. There is a KennethFejer-esque quality to the piece I'd like to keep. Edits on the leaves would be very appreciated!
I'll update this as soon as time allows, as I said I've been doing this between pixelling for work...and right now work has taken precedence,
