The dazzle set is the worst of the bunch. The fur on the back piece looks like frosting.
I actually think that's the best set of the bunch. The guy that made this has had a thread on polycount for awhile (way before Dazzle's model remake) and I thought it was already in the game. Valve's shop previews never do any of the cosmetics justice imo. They're all noticeably lower quality for some reason and I have no idea why, it makes everything on the store look ugly and bad when I've seen from polycount that that's usually not the case. I didn't even realize it was the same set until I looked at it more closely.
