Alright, overall, they don't look bad. Some of my problems are the conversion from 2D to 3D space. I will cover my nitpicks with each figure.
Kermit: I really have nothing bad to say about this figure
Robin: Again, nothing terrible here
Piggy: Her snout seems too long, and her hair covers most of her eyes
Swedish Chef: The hair on the sides of his head being a 3D model just makes him look like Bozo the clown
Camilla: Minor nitpick, I would've added on some eyelashes
Gonzo: Not a fan of the color choice for his nose. I would've preferred a blue/purple blend
Fozzie: I don't know why, but the whole textured and non-textured thing is not working for me. I just feel like they should've kept the body and ears flat like his face and arms
Scooter: Oh my...As happy as I am that we are getting more Scooter merch, he looks like the ending of Happiness Hotel after their picture is taken. Also, his hair just looks like a pile of carrots
Again, these are just my personal opinions.
