This might have looked better if the center of the fan were not visible. If you can, you might try re-doing this shot after unscrewing the cover and removing it, and tehn placing agaisnt a less busy background (the center fo the fan.) The cover is done incredibly well!
Wow, this is a great photo. In my own photo, I tried to capture the layers of curves getting closer and closer together, but I was only able to do so at the expense of emphasizing the curvature. You do both things very well here. Good job.
i really like the effect the coils make, here, but i think the background detracts from the overall quality of the shot. if you could somehow of gotten INSIDE the unit (an air conditioner?) and shot up, now THAT would be something. overall, a pretty good shot.
I like this photo. You have done a good job witht the depth of field. The angle from which this photo was made was difficult to keep the grill all in focus...
