Beautiful image Sam. The colors in the sky work well together. I love how the gems & the rich green landscape seem to glow. Very dreamy ..... best of luck to you in the contest.
So is this what the new improved South Bank will look like... LOL... kidding... nice dream theme, nice layout and colour... gotta say I havent had a dream like that either... lol
I rather like this, though it strikes me as more surreal than dreamlike. I like it as it is but, despite knowing nothing about this sort of work, since you mentioned suggestions, I'll add a belated one in the form of an observation. It seems a bit odd that the green orbs (I know they aren't orbs - too flat. More like alien Smarties.) are falling behind the mountains so neatly. It makes it look more like a film set with a poorly integrated backdrop than a landscape (or dreamscape).
But it really is very nice as it is, even if it isn't dreamlike.
