The colors are a big issue for the bg the character needs some more blending. Animation should actually be slowed down to more frames to make it smoother playing.

On the light animation for your text you should use the transparent gradient tool so that it doesn't have a black area on both sides of the light. Or you can make the text be the top layer and it probably will make it look right but wont solve the problem if you want to change colors on text in the future.

Hope this helps :P
