I'll be honest, I was expecting complete noob photos, but they're not.
1 is the best, but I would have liked to see the entire building without having it cut off at the top (tricky I know without a wider lens, but sometimes angled shots can work and they give you that much wider a field of view).
3 Confuses me with the ?windows? on the top, but I love the mural/ad on the building combined with the walkway. I would have waited for a hot young lady wearing similar couture to walk by to take the shot for symmetry. The guy in the shot looks out of place.
The rest are... meh. Nothing interesting in 2 and it's not sharp, and 4 is just your typical silhouette sunset shot, but without anything interesting again. Powerlines are a game killer too.
