Could have done without the extended title. (But I know sometimes people won't 'get it' without) I like the almost complete desat and the crop and focus are nice too. 8

comments: Nice different take on the challenge. I like your b/w conversion and the detail is really sharp (pun intended), (I kind of wish one a few of the bigger thorns were in focus but your DOF is good). As a thumbnail I almost thought it looked like a high powered electronic microscope view of a instect or something.
