I'm not huge on PVC busts, but I like the attention to detail that goes into them. Some look better than others, in my opinion. The Cliffjumper one looks okay. I've sculpted a few characters before. If I were to change anything, I'd cut the face a little more, but I can see what the sculpter was going for, as far as toon accuracy goes.
It looks like there are a few differences between the box picture and the bust included (colors, etc.), which I'm sure is subject to change when it comes to hand painted stuff like this, but are the fins on the gun cast that way or is the bust broken?
If it came in the mail that way, I might consider taking it back, but it's not difficult to repair if it was your undoing.
