Your attention to detail, and placement of realistic details in the shadows, is very good. You have done well to control and to well-use the entire tonal range of the image, with nothing blown-out and nothing black. The sense of the volume of the place, your choice of lenses and lighting, is very nice. The sense of proportion and Z-axis positioning of objects is believable. All in all, well-composed.
Particularly in the second image, it definitely has the feel of a sports arena on a winter night. The first image also has the feel of “the cheap seats,” and of being a long way from the action on the field that has either just-ended or is just about to begin. I like the fact that these are peoples’ points-of-view, not the POV of a network television camera covering the same scene. They are low to the ground, about head height.
In the first image, I feel that there’s just a little too much foreground; I’d crop the image very slightly on the bottom. Because this area is very close to the camera and hence close to the “eye,” the viewer will study this area more closely for details … and they’re a little sparse, a little “digital” there … when, really, this area isn’t where the action is or ever will be. You just need enough details there to establish place, but you don’t want the viewer’s eyes to become “stuck” there.
Very impressive work needing only slight changes.
