When I look at this photo, I feel hope and passion. I get the feeling that this represents something rising from the ground, from something terrible, and shining through it all - together. I get a happy, pleased feeling from looking at this, like something great has been accomplished. This is wonderful in the way that it makes the viewers want to stare even longer.
Technically..I don't think this photo has quite as much 'wow' as your other photos. Perhaps it's that the background is rather plain, and there isn't as much bokeh as I've seen in your others. I don't think this is necessarily a bad thing, because honestly, it helps us focus more on the flowers than anything else. The front left flower is in perfect focus, but the rest are a little blurry in comparison.
What I like about this photo is the angle of the flowers, how they are pointed upward and the light just cascades over them, or at least it seems that way. The colors are beautiful and natural, and compliment each other very well.
