Very nice capture. I would try and tone down the highlights about 1/2 - 1 stop. As for the yellow bit at the top, don't crop it as that will upset the composition, rather clone it out.
The flower is a little dark. I also wish you had not clipped the one petal at the top. You could mask it with a closer crop though. I played with it a little, hope you dont mind, not 100% happy with it but here. I think the b&w makes up for some of the lighting problems.
I guess you could crop 10% off the left hand side and it might improve it some. <shrug> Just my opinion. I pretty much like the original as is. The stag petal should go tho - with the clone tool like is being said.
