I would like to see a deeper, richer blue in the background, and maybe even a few clouds in the sky, but overall a nice photo nonetheless. Good job...7
For me, while a good contrast of sky and fire tree, I wonder if this would have a greater impact had the bottom branch been cropped out a bit more. There's a nice crispness to your shot.
Not crazy about the composition here. Think you could bump up the sky tones for contrast too. Still, well focused shot and the colors/shadows on the flower are nice.
