Help me to improve this, I know it has errors and i would appreciate help 
Overall, it looks pretty nice. Good modeling on the car.
One easy thing you could change would be putting a higher resolution texture on the floorâit looks a tad blurry. Also, for how scored up the wood is, the beams wouldnât have perfectly straight edges. The displacement on the barrels and the toolbox seems a bit strong, too. A tad bit of DoF wouldnât do any harm either. Idk what lighting setup you have, but it feels a bit too weak and uniform. Of course, you might be doing that to aid the ârun down garageâ effect.
Hope those ideas might help!
I really like the car (especially the paint and the headlights), but it doesnât really match the rest of the image all that well. The car itself looks much more comical (surrealistic) than the floor, the wood or the barrels in the background. Why not try handpainting the textures or looking for different pictures? You could also scale the barrels a little (they look a bit small in comparison to the tools in the background).
I find that consistency is often what makes or breaks the image (something I struggle with myself).
Good work, though! 
I like the look of the car, very nice. The oil slick looks a little odd to me though. The texture on the work bench and wrench holder looks large also.
Still, very cool.
Thank you guys 
you helped me a lot. I didnât even noticed the problem with proportions until now⌠And for the textures, I think it is a good idea to go with handpainted textures. Thanks
How cute! Fiat 500 or 600? I like the car a lot though it has very show roomy color. Thatâs not a bad thing, but it just donât sit right with the background. Itâs tooâŚMessy and clinically clean at the same time to sell the render. And sure the proportions are off, but I would think some other background would suit better. Just something simple and then build the details, but not too much as it would take the attention off from the car.
