Reives, that screen made my heart skip a beat. That's how awesome the concept is.
Over-exaggerations aside, I really like the idea of switching between animal forms. It'll add some much needed variation to the combat. Though, it might make players favor using Lunair more, don't you think? Unless... Dun dun dun!
Oh, and what, may I ask, is the timer(?), at the top-right, for? I'm assuming you have to make your selection within a few seconds? If so, then it sounds like a good way to keep up the pace of the battles.

I can't say why, but that screen looks very familiar.
Is the background animated? Those clouds might look a tad boring if not.
And what is the point of having it show your party members(in the bottom-right), when you can see by just their portraits? It seems rather unneeded. As if it's just there to be filler.
Looks okay otherwise, though.
