Great job overall. Just a few things to work on. I agree with Metal Head Bard that the armor looks flat. Second I would make the weapons more green as warpstone is used in everything including weapons and lastly the dwarf skin looks really off, too pink imho. But overall it looks great.
Looks great! The only thing I would work on is the armor. The red seems a bit flat. But who knows, maybe you were going for that. Keep up the good work!
