Ah yes, you had to choose between the lashes and the iris on the first one. I've seen that dilemma myself. I think that when you get this close, you have to have a ridiculous f stop to get a tiny bit more dof. That's why it seems hard, or different in any case. I love the shots though, especially the second one. Have fun experimenting!
Just read you have a new 105mm. I love mine and you got dome great advice a couple of days ago. The way you have composed these shots is very creative.
I need to find me a guinea pig or slave lol
