I missed this one in voting.. but I like it. A little soft where it could be shaper, which is probably one of the things that hurt this in voting. (the other would have been the fact that there's not a lot of "white" here.) A nice, unique, creative take on the challenge, and for a photo period.
This is a beautiful, lovingly-rendered image that plays a little loose with the challenge description, as I'm sure you realize: "Take a photo in which the background is white and the subject is predominately a "light" color". You're far from alone int hat, of course, but I'm scoring higher the ones that succeed admirably withint he stric terms of the challenge itself. There are quite a few of those. 7 from me, and let me say I love the poicture and the tonalities in their own right.
I know the thing in the center is a light, but what the heck is around it?????? Looks interesting to say the least. As for the picture...it seems a little grey to me. Not that that's bad, but that's the dominant thing that comes to mind.
