Knock-your-socks-off color!! Nice strong diagonal created by the stem leading to that graceful downward curve that continues with the flower and particularly, the stamens. The graceful backward curved petals add good compositional counter-balance. I would consider cropping in some from the right. Also evicting that tiny strip of green at the very left edge where the leaf curves and just touches the edge.
Beautiful image and I love the water on the one petal. Great angle of capture to show this flower at it's best. I would have wished for the entire leaf on the LHS and might clean up the darker line on the RHS. Lovely colour on this one.
