The focus is great and the closeup is wonderful.

I like the lighting. Looks like early morning or late afternoon. The composition is a bullseye so although it's almost a full-frame subject, it's a bit ho-hum. I think it would have looked more interesting had you angled your shot so the puff were located in one of the corners. Check out this one to get a better idea of what I mean: http://www.caedes.net/Zephir.cgi?lib=Caedes::Showimage&info=rozem061-1273485850.jpg%2Ci7.caedes.net%2C1549%2C1030%3AwcIQD3KxbjWmMHwkukr04A

Note how the photographer has centered the moth's eye, which is the focal point, in the upper left corner of the image.
