Hi!
I will try my best in this year Car Render Challenge. I'm self taught 3D modeller. My portfolio: https://www.artstation.com/krsto
I decided to create a concept car - I called it as "Signum".
I saw this car in my dream some time ago and I thought it's a sign.

About scenery, I thought that city at night with volumetric fog would be cool. Sorry for the quality of picture, but it's still a concept for setting and composition.

Of course there is a lot of work to do 🙂

Car WIP.

Scene and building WIP.

The result of another hours of work: tires, interior, brake discs with calipers and rims.

Tire and rim created using array modifier. Interior and brakes are simplified.

Recent work's progress. Car is almost ready. Later, I will work with background and lightning and composition.

White stripes or black stripes - that's the question 🙂

I decided to add some plants to the scene.

Yesterday I created cypress trees imitation with displace modifier with procedural textures. They're simple, but in this lightning and hazy conditions are sufficient.

Hey man, you have a lot of time to finish the scene - if I may, I would work a little bit on the car - something about the proportions isn't right, the "cabin"(?)" seems for me to small in comparison to the front and sides of the body, and I would push the wheels a litttle bit out. 

Keep working!

Thanks for suggestions.

I lifted upper edges of side windows (maybe 2cm) and roof a bit upwards. The proportions seem to the those of Dodge Challenger or Chevrolet Camaro. I think the wheels' position is OK.

I also attach a side view of my car 🙂

Post-production

The time came for post-production. I used compositor in blender.

Now I will upload final render.

I hope you'd like it.
