Leaving the chalkboard paint is cool if you let some of your buddies do some more chalk drawings on there once a month. It will be a moving art piece. Have them draw some neat designs, but not to over due it. Its cheaper than getting it painted. Save your money and buy a better suspension to drop that sucker. For the inside of the bay, the exhaust manifold is ugly as hell. either place the cover back, and paint it black with more flower doodles or get yourself some headers and expose that. As, mention above clean your engine bay.
Keep in mind, the words of one of my favorite architects, Mies van der Rohe, "Less is More."
You dont have to spend alot of money to make it look nice, just do as little as possible, but do it as CLEAN as possible.
