The only pictures where the Winston sculpt has actually looked "bad" was the early ToyArk pics (and the comparison photo for IAT's repainted sculpt with the light right in their faces). Every in hand picture posted of him, the paint app still does look too dark, but looks nowhere near the monstrosity that was in those ToyArk pics. They've all looked good in in hand pics, really. The only one I've noticed who sometimes looks a bit soft in detail in some in hand pictures is Venkman while in others it looks crisp, so the detail is obviously there, it just depends on how the light hits it I suppose. Ray and Egon haven't looked questionable in any photo at all, regardless of lighting.
So regarding the Winston sculpt I've seen three different groups of in hand pictures (IAT, Kobe, and now these) where it didn't look bad, versus one group of pictures (ToyArk) where it looked bad. Hmm.
And just a side note, I'm really surprised nobody has rearranged anything on the belt yet, such as moving the carabiner attachments to the other side, which is where they're supposed to be. Winston actually didn't have any on at all (at least in the scene when they first confronted Gozer). Rearranging the placement of stuff on the belt is the first thing I plan to do with these.
