Okay I am at a bit of a stalemate. Need some ideas suggestion and corrections.

Looks great m8
imo shadow should look something like this


EDIT:
cause with that one looks of in bg

I new it looked strange just coudnt put a finger on it ill try that. Thanks Gile.

Also the front bumper on the far side is looking like it's touching the ground maybe consider curving it a bit but maybe when you put the shadow it will look ok

UgraX3M thats because the shadow isnt good, shadow should look like that green stroke path.

Ta2man no problem m8, im glad that my litle sugestion helped u

yes i tought soo well hope that puting the shadow solves that and we are waiting for the next wip

After further review i have decided that this chop is not done and i really need strong advice i will do my best to make an awesome chop.

Here is an update some blur in the bg aslo set in a filter. I will start working some more on the body. Still not sure about the shadow.

shadow looks way better now, also it fixes the bumper problem..try making it a bit larger and a bit softer at the end of shadow it's to hard on the front Also i think adding some contrast to the car body may do the trick of making the paint more realistic try that out and let us see the resaults And one more thing when you did the blur effect dont make so hard edges on the car take a soft brush and continue that blured effect on the car edges but very little it will help the car to blend the background
Here i played a little with contrast and sharpnes and look what I got, i hope you dont mint i did this just wanted to show you what i meant i think it looks a bit more realistic keep it up
