There's no way round the very shallow DOF in extreme macro, I think (well, I can't avoid that with the methods I use, that is), and I like it best in the first photo here! I feel that one has a bit of a lensbaby effect and seems to be pulsating, what with the starlike tiny ... erm :scratch: white ... erm ... thin things, you know what I am talking about? I find that pretty original.
Other than that it's what Randog's saying: actually, if you get down to it, everything has already been done before, it is almost impossible to REALLY be original any more, and flower photos may be cliché, but flower macros, mostly so super-macros like some of these here, can still be original enough for me to spend some time with the picture. (Though, to be honest: 2 and 3 don't hold my attention for as long as 1 and 4 do, and 5 and 6 also are in the range of "normal" - but this is YOUR first time doing supermacro and macro photography, so for YOU it is a first. Well done on your firsts!)
