#1 could have benefited from a stack
#2 best overall in the series, imo
#3 nice clear shot, but not my favorite
#4 has the best composition and the makings of a great shot, however the focus is off a bit...
Overall good shots, if you find yourself really enjoying macro photography, then you may benefit from downloading a stacking program, such as CombineZP, its free, easy to use, and I think you will have a lot of fun with it, as well as see better images as a result! You will need a tripod in order to stack properly. Thanks for posting and keep on shooting!
