Well done!
The first one is pretty good, nice subject matter and a good feeling of energy. You probably could do well to back the highlights down a bit,
Second one is excellent, great use of repeating patterns and subtle human presence with a few small figures, a couple of cars and some footprints.
cropping a tad from the bottom is worth considering.
Re the second photo: I agree with Taveuni, you might consider cropping just a bit on the bottom, but I'd also think about cropping on the right -- I find the bottom right corner distracting. It might work really well in a square format.
