Ahhh TR, gotta love it. And no offense, but there are 100 apartment complexes that look like that but wtf do I know.

Now about the shots. They look like snapshots. I totally understand about the lack of sleep but if you're going to spend that amount on a camera, then take into consideration your backgrounds, where you're shooting, ect.

#3 seems a little out of focus and like Shane said, you could of brought yourself up just a tad to eliminate the background a little more. And the sun flares, I actually like them

Now get some sleep and try again lol
