Wow~I like this gun's buypic! About draw image, you can fix to little bit long, because this look like little bit short.This is you first skin, so this is good start.('w')
The buy image could need some more shading (it looks okay but it's still pretty flat) and generally everything needs improvement.
The kill image is a bit off, judging by the screenshot anyway.
The shell ejection thing (forgot what it's called) in the drop and kill images is misplaced, and the gun itself is shorter, compared to the buy and in-hand images.
And the yellow stripe in the kill and drop images seems to be in the wrong place as well, yes since it's so small it's a bit difficult to do it right, but still, you should be able to fix that.
Overall, it's alright. But it could need some more work.
