These are beyond the snapshot stage, that much is for sure!
You get close up to the flowers, you work with DOF and you get the focus fairly right. In some cases people may argue that DOF is too short (i.e. your lens is too wide open). I myself am not too much a fan of foreground DOF (blurred parts in front, as to be seen in Photos 5 and 6), I find it distracting. But the first 4 look good, and my personal favourites are 2 and actually 5, because of the colours.
