Please make sure you push the space key at least TWICE when you post the links to your photos so that there's a space between each photo and they don't run one into the other like they're doing now.
Other than that, nicely sharp close-ups. I like them. Only do I feel that you have to decide: you either want a real close-up of only the centre of the flower (like in the last photo), or you want the blossom, but then make sure you don't clip off any petals of the one blossom you have decided to be your subject (is what I think, but I'm only just myself... others may well think otherwise).
