I particularly like the last one. Wish the DOF were a tad deeper, though.
The rust is cool too, but I feel it is lacking a real subject. Maybe there is an old bolt / nail you can focus on, and use that as the subject, surrounded by a sea of rust?
#2 has a somewhat ugly background, and is a little soft.
#3 is soft and just out-of-focus, but still quite good. Nice to see spring is here!
Macro handheld is tough. Take
lots of shots to increase the chances of at least one being sharp. I often don't bother using the MF ring, simply lean myself forward / backward, squeezing the shutter button liberally.
