To me, it has a very 'dirty' look to it at the moment. I guess this is partly due to to the inherent 'messiness' of the skin, the rusty colour (which I don't like either
), but also to the graininess of the texture. The texture doesn't look like anything specific to me, which perhaps kind of bothers me. waaay to low-saturation and too purplish to be wood (I just can't see the wood at all), and too light and, again, purplish to be rusted iron (which it kinda resembles).
I like the drip stains you've put in places. Overall, I think you need to tame some of the various elements and give them all some more concrete purpose, as it looks a bit random and there is little 'dynamic' - by that, I mean there aren't strong parts and weak parts, it just looks like all the pixels are trying to show off and outdo eachother; extraordinary amount of energy, but not being very acutely directed anywhere in particular. This I guess is more a criticism of the original, but I just wonder whether, and where, you will direct that energy. I'll stop crapping on now.
