Once you start looking closely there are wonderful shapes, colours and textures to be seen.
I don't know if you are looking for CC, but in case you are, I have a couple of thoughts. If not, just ignore what follows.
It's very much a matter of taste, but for flowers I generally use smaller apertures than you used for these - all the way out to f/22 to f/32 sometimes, and most often in the region of f/13 or so. If you try this to see if you like the effect you may need to raise the ISO to keep the shutter speed up, but I believe you can go at least to ISO 800 with no problem with the 7D.
I'm wondering how you are focusing - manually or autofocus? For example in the fourth image from your second post the flower and the hoverflies are out of focus and the centre of focus appears to be on the front edge of a leaf to the right of, and behind, the flower. This makes me wonder if you are using multi-point autofocus and letting the camera decide where the focus should fall. If so, I'd be inclined to take control and use a single point, using focus and recompose where necessary. As with any closeup work, getting the focus centred at the right distance is important for good results, and multi-point autofocus can get it badly wrong where there is stuff going on in the background, which is often the case with flowers.
