i would say its because 1 2 and 3 are too similar..
you change only one thing to at 1->2 and only 2 things at 2->3

i think that knuffel has not enough changes in general though =/
maybe you add the pantsmore early, put the eary on an earlier stage, same goes for the hat and the tail...
a good thing would be to change the color more frequently, and do not make a completed other skin color in second stage.
some shadows would be great too :)

Hello

Could somebody do me a favor and tell my if he sees any smudges around this knuffel?

I can't seem to see them on my monitor (yes, even on a black/gray/pink/blue/brown/ANY background) and the more I try to remove these smudges that are invisible to me, the more I mess up her lineart
If this didn't work now I'll just have to give up on her

I'd be very grateful for some help

I don't see any smudges, I think there is just an optical illusion on small pictures, but when you actually open it in graphic program (tested with SAI and Photoshop) and add background, there is no smudges at all.

Thank you!
Then I'll try uploading her again now.

I think that's good changes. I remember looking at the first ones and stage two the only noticeable things were stripes, so this should be fine.

i think it should be okay now :)

I think both would be fine in terms of changes, but I think I like the second bunch with the gradual change of the tail. :) Makes him feel more like he's evolving than the other does. That's just me, though.
