Red rose in light and shade

This is nice lighting. Since it is a potentially a very artistic shot, I'll be a little harsh. I see the following defects:

1) I see the blue channel is blown off (downloaded the picture to confirm). I think this technique will provide better exposure with whiter shades of flowers (some which has blue in the colors)

2) The focus might have been on the closest petal... I see the need of sharpness on the shadows cast from the blue light

3) There is a flare on the stem which you might crop out

4) There is some compression artifact (is that due to downsampling?)

Hope I could be constructive.
