It's been a while since I've made a general feedback post here, and thus I have fallen behind. Shame on me...
@ Galactic Grunt: Ah, yes, I remember this fellow from before. I think I said something about him earlier too...
Anyways, I would have to say that that blue color doesn't look very good. Something about it is making me go "meh." Looking at the earlier color schemes, I'd say that I kinda see the aquamarine the most: if I am not mistaken, I envisioned that color when I saw your initial design. And, yes, back is beautiful. I'd say go with either one of those two color schemes.
@ Wyverii: Picking a polar bear as a play on polar... NOW I see where you got the idea. Should have been obvious to me... hindsight is twenty-twenty, I guess. Also, this design does not scream "water," so I think you've gotten what you were going for.
I personally would have prefered the metal that you had in the initial design, but I seem to be in the minority in that regard. Nonetheless, I do like the fluffy tail and, er, mane. The blue eyes look a lot better, too.
Personally, I think some supporting artwork will go a long way with this fellow: putting in the time to make some should bring this design a long way.
@ CyzirVisheen: A reverse angler fish? Why does that remind me of the Grand Fisher? Bleach references aside, I think the concept is really clever. From your artwork, it seems like the lantern body and the fish extension thereof seem to have two seperate brains if the picture with the fish biting the lantern's arm is anything to go by.
Since you seem to be fishing for comments in regards to the color of the body, I have a suggestion. Since you don't want to use blue, definately DO NOT use it as, ultimately, this is YOUR design. And I feel you: I don't like it either. Frankly speaking, I like the lavendar color you used. I also like the green as a second choice, but that may be just more due to the fact that green is my favorite color. The stripes on the antane make the design look more interesting, so you should consider keeping those on.
@ Doug-Just-Doug: I was wondering if you were sitting this one out as well. It looks more to me like you were hard at work brainstorming and desiging behind the scenes. God, I hate Bibarel's design so much: you have no idea how happy I am to see a better-looking beaver Pokemon. The design is kick-ass, to boot (no pun intended).
Your most recent, reddish brown color looks... okay. The original coloration was a lot better, even if it did match Bibarel's a little bit. Perhaps a darker version of the reddish brown might look better. Either way, as you are experimenting with different color schemes in order to get away from the "Bibarel-esque" coloration, I would have to say go with various tones of brown: it's not going to look any good with as anything other than brown.
Don't worry, though. I can't see much of a resemblence between your beaver Pokemon and Bibarel beyond the "well, duh, they're both BEAVERS" part. Your design looks more... agressive and battle-ready, whereas Bibarel looks like it doesn't have a damn thing in its noggin and just seems entirely unintellegent (whereas yours looks like it is has a fair bit of intellegence).
@ Rocket Grunt: You know, I actually had a similar idea floating around in my head to what you've got here. The only major difference was that the skeleton would have been made out of metal (as metal conducts electricity) if I had gone ahead with what was in my noggin. Yours, though, came out a lot better than what I would have come up with.
My only real suggestion for right now in regards to this fellow is that you ought to take the color of the head in the first color scheme in place of the head color in the second and leave the rest of the color scheme as is and see what you think of it. That purple head in the second color scheme just doen't jive, but the rest of the color scheme screams "perfect for this design."

Keep in mind that the designs that I am commenting on are not the only designs I like. All of the designs have some thought put into them, and I really like a lot of these. Paras Hilton's design remains my favorite, but I would have to say that CyzirVisheen's reverse angler fish design is a close second.
