Aristotle, you've got nice detail, good DOF and a pleasant BG - I just wish something more were going on...it seems like such a typical head-on flower image. Maybe a different angle or a little bit of something special in the BG would have added a little more interest?
Don't get me wrong...it's a very nice image...I just can't help but feel like I've seen it before. I would challenge you to take it a step further and find a reason for us to fall in love with this flower.
