1, 2, 4 and 5 nothing really grabs my eye...
3 - is a decent silhouette shot, but nothing special.
6 and 7 I honestly think would have been perfect candidates for an HDR try. Cool sunset in both, but the foreground while containing some detail, is grossly underexposed. Could have been a keeper with a well executed HDR.
8 is a decent shot of the bird, but I feel like it may be a bit soft, and I'm not digging the vignette.
