That is a very cute bodice.
The short-sleeve chemise thing is cute, but you might want to also make a long-sleeve, more opaque, slightly more period-correct one to help avoid sunburn. They're fairly easy to put together and, if large enough. make it possible for you to change from street clothes into garb in the parking lot.
For the cream skirt... have you considered putting a band of trim on it? If it were my skirt and I had the material, I would put a hem-band of the dark green trim on the bottom, to keep the bottom edge from showing the staining that you're going to pick up from the dirt. (Since I cheat, I'd probably use dark-green bias tape, ehem.) Then I'd make a band of the dark-green material to put about three or four inches above that, giving the bottom of the skirt a banded look. That's relatively easy to do, and is very period without getting too fancy.
You can trim your bodice with bands of the cream, if you like, too. Or make little 'wings' at the top shoulder part to serve as sleeves. While us Ren-faire wenches run around with our arms scandalously unclothed (except for chemise sleeves), there would ordinarily have been sleeves that tie onto the bodice.
