can you post the EXIF for the first shot? PRetty nice
Pretty nice. A couple comments...
1. Did you use manual focus? It looks like the first shot isn't -quite- focused.
2. Do you have a wider angle lens? Wider would be good if possible. (you're partly cursed here because I happen to know that skyline very well because I've shot it so many times myself)
Hail, fellow Bostonian!
