Avalon R..E..M..A..K..E

The lighting overlay on this looks really bad. First it doesn't make sense of where it is coming from, second lights reflect off of the dust to do this and in a cave, they would gradually get weaker as the effect reaches the ground. Second, there would be lights on the ground where the light directly hits.

Part of it isn't too much your fault though, RPG Maker 2000 can't do alpha transparency and it's hard to get any good sort of lighting overlay with the engine.
