Interesting. I'm not sure if the purple on the petals was intentional or not, and it's a little distracting... but other than that, it's a nice picture
I love the shadows and highlights in this - the only preference would be to shift the focus to include the front of the petals and throw the background more OOF - good luck
Neat and kind of psychadelic looking. I wish you would have cropped out the blue 'blotch' in the bottom right (or perhaps burned it out). Neat lighting, though.
