Sorry fella, I read it as you had gone out to try a friends macro lens. My fault.
I agree with getting out there and just shooting though. :]
I was maybe a little hard because I don't really find flowers all that inspiring most of the time. I think these work best when the background still has some detail and the main subject hasn't been completely pulled out of the surroundings. Pic 3 is the best for that. Pic2 still has the best colour though.
