You did a great job on the texture and painting. If I may ask, what settings do you use in Photoshop for your brushes?
My only critiques would be that the forehead on the face, is out too far. It should be a bit different, so that it will match the head position. Also, the right arm seems a little off. I'm not sure exactly what is bothering me there though, maybe size idk...
Overall it's very nice, great job. You have a nice style and it looks almost exactly like the original.
Thanks Vanhawk for the tips, its very helpfull for me , and answering the question you´ve made, well i used only one kind of brush(a common one with large size) and used my genius tablet to paint using it´s pressure sensibility...im not expert in doing this so thats the easier way i found to do it, this is my first time doing something like that so i think u can understand .
