this portrait nearly killed me while i drew it, but i finished it so… yeah :D

Hey guys! I need your help!

I’ve no idea how to draw the hair. The photo I used ends above the eyes so I had to imagine the haircut. I compared it with other pictures of him but it’s still hard. So do you think it’s okay the way I sketched it? Or is it too fluffy or anything? Also, I’m not sure about the forehead. Isn’t it too short?

Please help?
