Your perspective and composition is great, but your use of HDR is so way over the top that this doesn't even look like a photograph any more. I guess I'm biased, sorry.
topaz adjust?? this is a bit too much for me. I love the feel of the picture as a whole, but the tree it self gets lost. This being the Tree challenge, it should pop out more. I gave you a Five.... usually i give bad scores to those pictures that don't meet a challenge fully, but your photo shop work is nice.
