this style kinda reminds me of Kritez tags, take that as a compliment ^^

I do feel though it could use some shading to help with depth here, possible if you have gotten to the end of the tag where you have flattened it, just go ahead and put a gray layer over top and put it on soft light, get out your burn tool and lower the op and lightly work around soem places, example would be in the palm of his hand, lower part of his chest and face under the cape a bit on the left.

I would also suggest taking a soft black brush on low op as well and on a new layer just lightly going around the edges, you decide if you like it on norm or on overlay after playign with the settings.

These are just tips to help out and in no way am I saying DO IT!! but yeah, thought I'd give you soemthing to think about ^^

Good tags tho
