what a beautiful place to be shooting. compositionally, your image is fine. there are some things that could make a difference, though. the details in the image just aren't that sharp. also, the harsh, midday lighting doesn't give it the same drama you'd find earlier or later in the day. sometimes, you don't have a choice: you're there now, and you won't have a chance to get back to it at a different time. but, when you do have a choice, try to get your shots when the lighting can do more than wash out the natural beauty that's in front of you. all the same, nice image. good luck!
Great subject. Tough to get those wildflowers to brighten up - even when you know they are brillliant, they sometimes don't show up that way. Might try boosting the hue/saturation a touch on just the field (advanced rules, you know). Still, a lovely image.
I think you had a nice idea for a photo here, I like the foreground and the range of colors from the reds, to greens to the blues of the sky. In my opinion though, it's hurt by the time of day you chose to shoot this. The lighting is a bit harsh and flat. Looks like it was taken around mid-day. I think if you shot this scene closer to sunset or sunrise, it would make a dramatic difference.
