Methinks you still got a couple of focusing problems when you move up close to your subjects?
And these are scanned prints, aren't they?
Who did the scanning for you? Yourself on a flatbed scanner at home? That might account for the softness of the close-ups, too then... :scratch:
Though I must say that I like the concept of the close-ups here, they quite nicely concentrate on one subject and are not too "cluttered" (haven't I used that same word in a comment to your other thread on the spider before?).
In many cases (so I think), when you move up close to things, it is better not to have anything large in front of that intended subject with will get all blurred by a large aperture and later distract from the subject. So if there is another leave in front of the leave that you focus on, maybe flatten it or take it away much rather than leave it in the pic as a blurred blob. Just my thoughts.
