Thanks all. I did have the same feeling about the out of focus stamen... I just liked the colours and shapes in the rest of it enough not to let it bother me.
Both were taken with an M 50mm f/1.7, with close up filter attachment. Lighting is from a fluorescent light fitting with four 2ft daylight spectrum tubes in it, that i'm finding very handy for close up work.
On another note, I had a nice surprise when checking back on the exif data (it's been a good month or two since I worked on these). One of the photos was on a tripod a ISO 100. The other, handheld at 1600. I can tell now that I know, but it wasn't even apparent on the prints I had done.
