Congratulations on your success. It is a lovely flower and you managed to capture it pretty well.
Having said that though, please forgive me if I might sound nit picking, but next time you get the opportunity to photograph this flower, 'order' some light to go with it. At f/3 and 1/30 shutter speed it seems that you had some rather bad light to work with although judging by the BG is looks like there was ample light. So I am a little confused why the shutter speed went so low with such a wide aperture. A little fill-in flash could have benefited the shot as you needed to get some more DOF to get the flower completely in focus.
I would like to refer you to a critique I did for Alp Capa (ArcapA) which you can see here. Also read the reply I gave to his reply. Maybe that might help you somewhat. I realise that the advice given there sounds mostly like it is only applicable in a studio type environment, but I am sure there is sufficient other info that could benefit you.
Go for it and I am waiting to see the improved version.
Well done though and I hope I did not dampen your spirit. Please see this as a postive critique to try and help.
