Nice work, but lighting on this one seems a bit strange, causing the rocks to look too uniform and flat. The distant foliage looks a bit too grainy and synthetic, likely due to the lighting as well. I'd look into adding some translucency to the leaves, petals, and stems for all the foliage. Get that and the lighting dialed in, and the image would shine.
Anyway, I can see the makings of a great TG2 pro coming up!
