You certainly got the colours bang on - I like them very much. However, you have the emphasis the wrong way around - the trees have very bold leaves but very faded trunks. To give the effect of distance, the leaves should be the same intensity as the trunks. Also, I think you need more (subtle) detail on the distant leaves. It looks too much like you just slapped a filter on a Bryce image and the 2D filter doesn't work that well with an image with depth like yours. If you're going the postwork route you need to give that mouse a workout and add some detail where it's needed. IMVVVVVVHO!!!!! But it's still a nice pic. Sort the leaf intensity and it's something I could see hanging on my wall.
