I agree with digital that the text should be improved.
In general to me the effects used (on the text) are too much representative of a cartoon, which doesn't work with real cars, etc.
My suggestion would be to work on the text, keeping in mind you want it to be a part of the image, no just on top of the image.
# 1 is rather basic, the car blends well with the black BG though.. my personal opinion would be the anime guy doesn't work with the car. 5/10
# 2 is nice except for the text.. if you're able to get the text working with the image I'd probably give it around 7/10
# 3 My opinion is that too much is going on in the background, and perhaps it's just being awake at 2:30 am but the text doesn't do any favours on the eyes and in general there's too much going on
#4 Is my fave.. The text isn't horrible except I feel it is a bit too exagerated.. calm it down a bit, perhaps a different gradient.. 7-8/10
