I really like the first and last pictures a *lot*.
The nut + leaf picture is hurt a little bit by the 2 subjects. Seems like if you cropped in close to the nut and had a tall picture of the leaf you could frame them and put them up on a wall in basically the same arrangement you have now and it would look really good. Fuzzyness of the background might not work on the nut though.

Anyway, *really* nice pictures. Keep it up!
