Personally, I loved the color also. I've never done flower shots before, and a really never thought I would b/c thats not really my thing. Just testing out my 105mm Nikkor micro VR i just got. This was shot handheld..
maybe crop a little off the left? Only reason i say that is because its dark and dull, with all of the brightness on the right side. I dont know, just the left side draws my attention away from the flower
