Good shots but are they really macro other than #5?
1 would be very nice if it was closer.
2 would do with a better crop removing the top portion so that you can see the repeating patterns of the leaf only without distractions.
3 has too much to see.
4 afternoon sun or too harsh flash? Need a softer light.
5. cropping is not right. there should be more of the top and bottom so that the outgoing orange lines complete and do not get cut off. the right can do without the small empty space.
actually i was playing with my tamron 90mm macro. the close up one are with nikon 6t n hoya +4 filter.
yeah, my flower shots are always OOF. first time i manage to get a fairly good shots. really, more practise will definitely improve and get what you want.
