fnaqzna: I like the color in the 2nd image. I'd suggest a wider shot for the first two rather than cropping off the edges of the flower. The third one looks good.
Chamaeleontidae: I like the second one better, The background in the first is a little busy.
Here's three I'll post
1/40 sec @ f2.8 200mm on a dark cloudy afternoon
1/125 sec @ f2.8 200mm
I like this one because of the progression from buds to flowers
1/400 sec@f2.8 105mm
