(WIP) Chilling in the parking lot (Patreon)

At the moment I'm working on an illustration as a promotional piece and I'm trying to take my time on it and do it right. I thought I'd show you my process so you don't think I'd disappeared. Still not sure I'm done with all the base aspects yet, but this is what I've got so far. Still gotta finalize some partsand then get into lighting, shading, and detailing.
Debating redrawing the far background buildings, and I still need to add a transparency layer to the windows of the car so it looks like it has them. What do you think?
