Can you guys look at Exiles of Tharna?

I'd really appreciate if you guys took a look at this. Its something I've been working on with a friend and the idea owner for a while now, and we need someone more competent than I am at sprites. You don't have to do that, but that's the main concern right now. I mainly just want some input.
