One thing that stood out was the brick building in the back, you can tell it's tiling and it's extremely boring, need to add some corner pillars and ledges to break it up. Overall I like the composition it just needs to be filled out, and I don't think a few trash cans are going to do it.
Thanks for all the replies. I will try and break up the brick building more by adding trims. I will also be bumping up the spec as RexM suggested. I had thought about going zombie apocalypse but decided I want it closer to just a small section of a city before any disaster. I might go back after and create a post…
