I absolutely love your shading. Something about it just feels right to me. The brow bone, face, neck, all of these I love. Great expression.
I feel like you could have done a little more detail with his outfit, especially with the golden and red thing on his right shoulder.
Overall, pretty good :)

Isn't he going to be in the Deadpool movie? Also his jawline is very masculine, and his face looks awesome, especially around the eyes.
