@brackeen: i like the ideas behind each of the photos. the first photo seems to be a little bit overexposed and the subject (bubble) is not in focus. the second photo also seems a little off focus--the focus point seems to be located below left of the bug rather than being on the bug itself.
keep experimenting with the lens. would be cool to see the progress as you master using it.
here's my contribution...feel free to rip it apart. :P
