Hey photogs,
I've received some "soft" rejections recently and would like to know how to improve the photos. Here in South Florida during the winter season we get some fabulous light in last few hours of the day. I've been shooting with a low ISO to keep the grain to a minimum, but when the light gets soft (even just a little) I seem to get rejected. Below is an example. Is this something I can fix in editing, or in setting up my camera.

Shooting a Canon T2i with a Canon 70-200mm F/4 L ultrasonic. Thanks for all the help in advance. It wasn't long ago I struggled to get any photos on this site, and yet just the other day I had 6 uploaded in a single day. Most of my success is due to what I have learned from reading the manuals and reading what you all have told me.
