I love the dark and lonely feeling that this gives off, you can see the pain in his eyes and more so when you add the coloring in there of the `RED`. I love your wings in the red too, but I think they need a bit more polishing, more shaping, this part feels a bit rushed. I do think it is good overall and having the original beside your try at coloring with photoshop was a nice touch. The BLOOD here and there over him also worked out well and gave this its darker element. I love the flow between the before and after art and it all works good. I wish there was more color, maybe more line work over the greys, darker elements here and there. I do love this though.
~~THINGS TO IMPROVE ON~~
More colors, more work on the wings, good job for coloring though.
