A nice flower shot; I thought the lighting was a little hard at first, but on second look, it's necessary for the clarity of the petals. I like the framing and depth of field.
I think the composition would be better if you picked out some more detail of a particular flower rather than trying to get all of them. The most interesting detail is in the stamen, Maybe a top-down view would get more out of the subject.
I'm leaving pretty much the same comment on all the flower shots. Flower shots aren't very original, so you have to make up for it somehow. I think originality is overrated, but if you're going to do something normal you really do need to separate it from the pack in some way. Although it's a nice photo, it isn't amazing.
Its a nice close up macro shot, the red is vibrant. I'm not sure what it is but the composition is a little lacking. I'm not getting a strong emotion from your picture.
