Kind of boring, sorry, but very nicely captured. White background is really white. You've done much better than the majority.
Just because I said it was boring, doesn't mean I rated it low. 8
Interesting image, it is very dynamic. I'm having to stretch to make it meet challenge, simply because though it is lighter than some things, it is still fairly dark in comparison to the white background - the wisher things have a very brown tinge in much of the image. I don't know if this is an effect of the lighting used or not as there do appear to be some lighter colored ones. The focus is a bit problematic for me because my eyes are being drawn to the foremost wisher and it is very fuzzy, whereas some of the puffs in the clump further back have better defined features. I like your composition, it looks good tucked in the corner and your border is simple and doesn't hamper the image at all. Lighting looks good. I gave a 5.
