It is a little centred, like Jeff is pointing out, a step or two to the left might have helped, but who knows what would have crept into your background then? Hm? Oh well... the colours are impressive, and with a flower like this one I would hate to lose the colour, like Jeff is suggesting, but that is just me. Maybe the more abstract variety of a black+white photo would force us to look more and most of all IMAGINE more...!?!?!?
