I like the depth of field/focus work you did on them! Those are very good shots, the top one is amazing, capturing how alive a pond can be. What camera are you using, and what lens?
Love the detail that a good DSLR will provide in a picture. I have a Nikon D80 that is in need of a trip to California to be repaired; the Menu stopped showing up on the screen. It's still lots less expensive to send it in for repair, than it is to replace the camera!
That's a killer lens that you've got for your camera -- I envy you!!!
