the merfox looks really cute. She has a nice furry pair on her chest. Great fins on the sides. They look good thin. You did a good job with the cartoon action pose for the squirrel, I'm happy you're getting those down. He looks about right I think, though he's missing something between his legs <winks> He seems to be a tad confused about whe he's in a picture surrounded by water and two sides and a flaming mech below him. Neptune looks good, a lot like the Little Mermaid's daddy.

And yeah, the mech thing does look gundam-ish :)
