Nice improvement
I see you fixed Shepard's mouth, it's definitely better but I feel as though his upper lip should be a bit smaller. I noticed you added some touches to his armor as well, which make it look better than before.
The background is much better as well, but I still have some nitpicks. The railing perspective was pretty well done, minus the left corner where it seemingly shrinks a bit. The buildings look nice, though they seem a tad too flat. The lines for the far right building are noticeably off as well.
Overall, a clear improvement from the last.
