Any suggestions on what can be improved or added would be much appreciated.

Base:


Chop:

Awesome work mate, loving the atmosphere and the brutal JDM/ time attack style mods on it.

As for C&C, Here's a few which I spotted on first quick sight. ( sorry for the big pics)
-The tape on the lights can be a bit thicker.
-the Carbon fiber bits are actually very nicely done, but the bonnet can just be a bit darker.

The copied / pasted front tyres are are a tad bright, I can see the change from donor/ base image, to fix this, Just lightly use the eraser tool on the tyres, so they blend better together.

The bottom of the side skirt can use a bit of shadows, so the part dont look so flat.
Using the Burn tool on photoshop, drag it along the bottom of the skirt.

Also the far front bumper can use a bit of reflection from the surrounding/ background.


Also, defiantly dont see too many Nz choppers on here, so welcome.

Haha, thanks heaps for that, you really didn't have to make the pictures but very helpful
