This was just a personal project I had worked on a while back. I created this design on Photoshop, it would be brilliant if you guys could give some feedback
Looks awesome! I really like how you nailed his expression down. The only thing I noticed is that his left hand doesn't have the black outline that you used for the rest of his body. Other than that, good job.
I second what @John Sword stated above. Overall it looks great work and if I had paid for it I would be pretty satisfied IMHO.
Just so you know, it's photo manipulation. But, even with that, I like the iamge. You've managed to keep a good balance between shades and detail. What I would suggest is to hide the details in the forearm, try freehand shading if you have drawing skills. My point is that it's such a beautiful pallet and color, it's a shame the original "presence" of the photo can still be felt.
