Very strong contrast. I like how the veins are clear, and the curls at the ends of the petals/leaves (sorry I don't know which xD) add a bit of mystery, especially since they are in the back where they aren't completely visible. The only suggestion I have is that perhaps the first petal on the right of the part (the middle~) should be in focus. I'm not sure how it would look, but it's like the viewer is being led further back to the other two focused petals. x3
