Generally, it needs to be sharper and I'm not talking about sharpening tool. You should try using smaller size brush as smudging with big size brush turned your image blurry. Green glow on eyes is ok, but one on mouth is not. You can hardly tell it is fel orc under that mask. Red in background could be more subtle, it overwhelms the image.
When it comes to wc3 matters, it reminds me more of wildkin (it seems you cropped out from original wyvern texture), but that's less important than technical stuff you should fix.
