Neat!
I'm excited to see Warcraft-y models from you, Mike. You've got loads of talent as seen in your other works; I'm just more particular to stuff like this. : )
A pure & simple model, quite elegant. I love zany Goblins and their contraptions, rickety as they are. Perhaps my only thought would be that this did not go far enough. Throw a few more nurnies on there, perhaps... And in terms of animations, he could use a bit of spinning I suppose. (Question: does he spin to face his target? That's really important IMO).
Beyond that, there's not much else to say. Good model. Love the well-placed "WELCUM". xD
