Your photos are spectacular. I especially love numbers 1, 2, 4, and 15. All of them have a certain quality that really draws me in. For number 15 how did you get certain parts of the photo softened? Is it something you did with photoshop or another program? I love the effect it brings to the photo.
All of your pictures are intriguing. I would recommend adjusting the brightness in the first and third photos in order to darken the white space of the sky. There is something missing with all of the negative space. I feel that the lightly darkened sky would enhance the look of those photos.
