This is it, after a long time of thinking about it and asking many people I decided to upload this version.
For those of you who said no detail under the car was good... REJOICE!!!
For those of you who said yes to the detail under the car, well, I guess I think it doesn't need to be so complicated to know its a car, and that there's no source of light comming from bellow the car, so, being logical, in real life you wouldnt be able to see any detail, since the light is comming from behind the car...I'm sure you'll understand, This is still great! (at least in my opinion).
Thanks to everyone who helped in the process...
