I think the strongest photo in the series in my opinion is between #4 and #2. I would have been interested in seeing #1 from a different angle the silhouetting is nice in that one. Also #2 has some very nice lines working for it. # 6 has the black bar at the bottom which is sort of a distraction, maybe a closer zoom or tighter crop for that one. I like the series, your off to a great start in my opinion.
