This critique has been left on behalf of #Graphite-Gods as previously requested. Sorry about the delay.
I have to say this is most impressive and I'm amazed at the size of the work. I love the dark tones you've achieved in the car and they work well in contrast to the lighter treatment of the background. There are a lot of lovely subte touches in this, the brickwork, the building in the distance, and the reflections on the boot. I like the bright highlight on the rear window, but I'm less sure of how dark the glass appears next to the highlight (without seeing the reference, I can't be sure if this is how the area appeared). There really is very little to critique in this drawing as it is a most accomplished work, you've made this vehicle appear like a very classy car
