The composition of this shot is awesome. All of the lines nicely pull you into the centre of the flower, which is nicely off to the side. Very nice.
I think this image could be improved with a quick sharpening in photoshop or other similar program. Also there is that damage mark on the right side that could be removed with a healing brush. I would personally also be tempted to up the contrast, but this im no sure about. My style is to have more contrast in a shot, but maybe for this one the way you have it is better. I'm not sure. I am now just writing what comes to mind.
Anyways,I'm not sure if these are possible suggestions or not due to your software, but i thought id suggest them anyways. Very nice work on this one.
(edit) I just went to check out your gallery, and this is your first one in there, so i thought id welcome you here. I look forward to seeing more of your work.
The colour and the detail are just lovely Hannie. and the whole pictue is a delight to look at.
I would agree with the others above that the damaged portion could be removed. Apart from that it is perfet in my eyes. I love it :)
