the picture looks fine... but i think the light's colour is wrong.

usually if u want a black bg and if u were to use those type of "light motion", i think white, red & dark blue would be better.

as for your lights idea, you could always add some "sun" glare into them which would rather effective if your art tittle is "lights".

jz my one cent...
