Cleaning up
Details
Added in some very basic tones and shadows. Debated a long time on whether or not i should bother with color.
Decided to do color. Started with a basic gradient, red on top, added pink to the red for the middle, and a darker/cooler red for the bottom.
Highlights.
Added shadows and details. Got lazy on the wheels and took them from my reference photo, may or may not revisit them at a later date... but I probably wont.
Added that typical "showroom" black background.
And here's a photo of my setup and a bunch of reference images I used.
