the shapes look good, but the seams look like the material is only a 3d plane, not a solid metal. The ends of the sheetmetal should be bent in, so there’s actually some curvature. The shape of the car is very nice, but the metal looks unrealistic in those spots (which should be pretty easy to fix with some extra edgeloops and some moving, hell you might get awat with only a solidify modifier)
I was wondering about this in the small image, then I clicked to enlarge it and it’s really obvious in the roof, the doors and above the front fender
edit: added screenshot of a car model I worked on for a while, the extra edgeloop and the small extruded edge make it look like it’s solid
