Camouflage: The problem with this is that the print goes straight across, almost like the artist just set the layer to overlay. If the pattern on the mane just bent with it a bit more, this would be perfect. It's not awful or anything as is, not even really bad, just a bit low-effort.
Polka-dot: I get that they're trying to use different solid colors on different areas, but then why are the tail and mane the same? Either make everything that shade of blue or make the two different colors. Other than that, it's just eh. Nothing amazing, nothing bad.
I honestly really like the colors on the Camouflage Gnorbu, very, well, camouflage-y, but still pretty and whatnot...it's too bad it goes straight across, it does look rather low-effort.
Polka Dot...eh. The bright or dark colored dots really bug me, but I guess that's on other Polka Dot pets too...maybe just not my color.
