Simon Edwards - Captain Capilano

I relaize I may be quite a bit late, but here are my designs thus far anyways. They are all varying permutations of the same general shape, with a few exceptions.

Feedback would be greatly appreciated. I really need to get further away from our friend Michigan J. Frog...

Regardless, my general vision for the good Captain is this: He would appear to be a regular frog, perhaps reclining peacefully upon a lily pad or beneath a park bench, and would only morph into Captain Capilano at the onset of UN-GREEN attitude-- think Superman/Clark Kent, Peter Parker/Spiderman, etc. etc.
