I think you need a better tyre material and you should do the sidewalls with a bit of bump map. Other than that it's amazing. Did you buy this HDRI and backplate or you got it for free from somewhere ? It's amazing ... I wish I had it :)
Yeah, you're right. Thanks for the reply, I need to improve the tire indeed. HDRI is from smcars packages, the background is from deviantart, I just sent an email to the owner for permission.
