Yes sir, a job well done
I think the guy below has some wack OCD, his criticism holds no water.
This has some real nice colouring, a balanced mix of soft and hardas well as a professionally restricted colour palette. The lighting is perfect for my standards, it's necessary for the dude to be visible. One fat problem is that the dude has a big head which throw proportions out, making his hands and torso undersized. Unless I'm really comfortable, I put a reference pic right beside my dude. Do that! Also, the less detail (wrinkles) you can get away with in the hands, the better they look. Unless you want old-man hands. As for the dragon, it's kind of a shame the wing tears are so pixely, it'd look much nicer if you smoothed the eraser marks. There, some constructive criticism. Well done.
