Nice digs.
The picture overall is well done, but there are some issues that are bothering me:
-The head seems to be tilted down a little too much for the angle he's swinging at. It would seem more logical if you had him doing a downward cut with the sword, but instead it just comes across as awkward.
-His shoulders and helmet, while realistic, don't match up to the game. You got the season 7 sword down pretty well(kudos by the way), the shoulders and helmet seem slightly smaller than what's in the game, making it seem like he's kind of overweight due to a bit of a gut sticking out.
Other than those issues though, I like the picture. It captures the ferocity of the warrior pretty nicely. If you've still got commissions available, feel free to contact me. I might want one of my characters done.
