That one drop of water totally makes this image special, Aidan. There is one petal towards the top third that has a brighter side to it - I would probably tone that down a little as it competes with the drop of water. Beautiful colors here and a lovely, soft composition. It really sings...
Love the shallow dof and this is a great image. Ditto on the lovely colours and I like how the focus is on the red/pink tips. The water drop is the cherry on top.:)
Wonderful color, lightness, composition. You achieved much with so little. I like the angle of view and that one drop. I agree with Mike about the red tips, and with Jules re the little area that is brighter. :)
