Out of the three you asked for comments on this one is the hardest. Perhaps because it is the best of the three. The centered composition works great here. You have lost some detail but I think that is what you are after and it works. The thick border works well here. The clouds are a nice touch also. I also want to mention how I like that the dog is looking off to the left of the photo and not directly at you. This to me adds character to the whole image.
Oooooh I love this one! I think it's great!
You really need a very calibrated monitor to get it, so I bet you'll hear a lot of "too dark" comments. But it's simlpy gorgeous as it is!
I love those weird looking shadows, and the bright lights. That angle also adds so much to the interst.
Wonderful wonderful wonderful!
With the angle of his head, in b/w, unless you know it's a dog, it's hard to make out what you're looking at. I would love to see this in colour....looks really interesting!
