Flower photography (first post)

[Arcturus]

I've just been lurking here for a few days, and this is my first post on these forums and one of my first photos (using a low-end p&s). Tell me what you think. I have applied an unsharp mask, adjusted curves and contrast and upped the saturation around 10 in PS. Also this is cropped, so if you want the original i'll post it. How could this be better, both in composition and post-processing? I like this photo but the white flower poking through the corner in the lower left bothers me, i'm not too sure how to crop it without losing the main focal point.
