Very nice photos! And I totally think you would love a macro lens :-) It sort of makes one wonder whether those v-shaped leaves are intended to channel water or hold onto it.
I like the composition in the first one, but the leaf texture in the second image is nice, and you get a little maginfication through the dropplet. Very cool.
It's amazing what a little movement makes in texture - I moved to the other side of the plant and the leaf texture was perfect (in my mind anyway), but not the first one - so it has to be the way the light hit the plant from the other side.
I probably would like a macro lens. I'm very curious about things up close - probably bc I can't see up close :)
Thanks Mark.!
