I love this series of refraction photos, great composition and focusing.
Just out of curiosity, are you focus stacking to get the refraction in the drop and the petal holding it in focus, or do you just have a deep depth of field from not being too close in?
I've been thinking of trying photos like these, but focus stacking seems a little too fancy for me.
Oh, just a little piece of unsolicited advice, you could probably minimize that white bar on the droplet (from your flash?) if you use a polarizer for these kind of shots... Not that it's a huge deal, but it's a minor touch that couldn't really hurt.
