Hi everyone,
after a few months of using blender, I decided that it’s time to get some critique ;). Comments for improvement and opinions are highly appreciated!
Headlights:
I think the headlights miss some visible “interior” like bulbs, dont they ? Look a bit opaque now… except for the enabled lights. Or is this intended in newer led headlights ?
Maybe the light glare / blur is a bit too high.
Tires:
Front tire profile looks appropriate, rear tire profile is missing ?
Model / Paint:
Model and car paint look good from this angle,
Maybe the reflection on the lower part of the windshield and above the left headlight is a bit off. and you cannot see through the windows 
and you have the same problem as me, the door, its too flat. the a5 has a defined line on it
headlights are missing a lot of detail and are mostly blank. look at this reference:
the headlights should be whiter
blank license plate is wierd
logo should be more 3d and shinier
tire tex is too small
the a5 has a line on the door
some other stuff is missing but it is tiny anyway. like others said the glass is not transparent enough.
very nicely modeled though 
Hi,
thank you all for your comments. I will spend more time on modelling the headlights and some other things I’ve noticed after posting 
If I reduce the reflection of the windshield I should add an interior, so it could take a while before I post an updated version
more images should be posted if a geom. validation should be done. your carpaint is a solid start but could be improved. try to work with a 2-layer material. the overall renderscene could be improved. i would google something about “Studio renders” for a studio render i wouldn bank the camera. hope this hepls a bit
This was a double post and I couldn’t find the delete button, sorry for that
Hey, thanks for your critique. I added some details (it’s now a RS 5) and corrected some modelling issues. I am still working on the car paint and the lighting, so it’s not perfect.
Again, critique is appreciated. 
It’s looking good! Don’t forget the fresnel fall off on car paint
Also with reflective paint reflective, don’t forget to soften the edges on your light cards to emulate real life studio lighting.
Can’t wait to see the new updates! 
there are tiny bumps here and there.But the model itself is looking good.
In first render u have some issues with the lightning, the second render seems the same. Also the material setup, but you already told us ur materials are still a WIP. Anyway looks good, keep up the work. Try to google for some car studio renders. Use an HDRI photo studio environment. You can find lots of it on HDRlabs.com and…google.com
