I don't know what "lolbooth" looks like, but the concept - individual or groups against a background recorded digitally, has been around since at least the mid-1990s. Set up a background, balance the lighting, add props, and shoot. At the same time this could also be done against a green screen background and video taped. Then add new digital backgrounds to any theme or request. It's a good idea, and a money maker, especially for bar & bat mitzvahs.
Just about any website design, even the cookie cutters, is better than what you have as far as sharpness goes. There are so many. Do a search, or check out some of what the FMers use.
Couple of things: It would be a good idea to take the word "lousy" out of this statement on your site.... "Don't worry about loosing your lousy printouts." Also I don't like the song. Unless you have paid for permission to use it, you could be sued. BTW: There are better royalty free songs.
