I dont have any idea so i make this thing,

base



Work

Mh sry base one lot better
Shadow to soft
Not fan of the Lens effects
Back looks strange and what that black Stuff on right?
The wheel? Mh... off and not on right Place
Rear wheel to small

Sry for that cc bro

But lot work for a quick Good ideas

Good idea but poor performance!
- Work is "fuzzy"
- No shadows on the painted parts -> rear wheel arches
- Wheels -> Front they probably stole? Did it fall off? Because you can see only the outline of the rim ...

Mate , u have to progress i'll give you some tips during the contest but ... you use Photoshop ??
And try to use always a big size base ( > https://en.wheelsage.org/ )

Example for your IS : https://en.wheelsage.org/lexus/is/i/pictures/ssrs5l/ (2100×1116)
