This theme makes me think of Animal Crossing. I like it!
I would have to agree on a lack of contrast, though. You've got bright text on a bright background! The text should be darkened and/or made a different colour that better contrasts.
Maybe a forest green (#44A248) for the green text, and an indochine orange (#C36F00) for the orange text? [I'm getting these colours and names off a website, by the way.]

I think the font color choice is the only thing holding this back. The colors of the text are hard to see, so darkening the font colors would be the best.

Too Distracting, goofy decorative vs enhancing power users by excellent UX design
