Otter Power Currently the fur is more of a dark purplish color. I think there may be a better color pallet out there, but this one works well enough. I would recommend maybe making the shell-hands a different color or shade from the fur though, as currently they're a little hard to make out.
Involuntary Twitch I dig the Elephant idea. As a couple others have said, the harpoons look a little out of place. I think you could probably remove the harpoon tusks and focus more of your attention on the water cannons and create a stronger overall theme for the pokemon.
Mystery ZOroark Your design seems a bit complex to me. The gems don't really add enough to the concept to seem worth inclusion, and just create noise in the design. Maybe if I knew more about the Egyptian traits you mentioned I'd be able to justify more of the design choices, but currently there's just a lot happening and I don't really understand why. You could probably improve your concept by focusing on two/three important elements and using those to re-focus the design.
PixelMoniac_ Nice idea with SHJ, although currently I feel the main body is lacking in flavor. Maybe try seeing if you can incorporate more elements of Steel into the body? Maybe try to draw more attention to a particular frog species even? There's lots of potential here.
Sunfished I like this design a lot. I'd like to see supporting material for it. Only thing I could really suggest is potentially finding a way to make the arms and legs a little more interesting, but otherwise it seems pretty watertight.
Wobblebuns Its funny because I had been going in the directions you advised even before I read your comments. Great minds think alike, eh? As for your design, the supporting material looks great. Of course I'm unnaturally biased towards liking anything that even remotely resembles Virizion so there's that. I look forward to seeing your alt-designs when you post them.
