It looks like you just got started on this. I also found the lighting too dark. I hope you will add enemies, and better lighting. This could make a neat arcade game. Movement, and shooting was really cool. Work on adding some enemies, maybe waves of enemies getting more difficult, and power ups too! This has huge potential, and I hope you will keep working on it. I've just moved in to 3-D, and it's awesome, but does require allot of learning, so keep trying to improve.
