Great photo! My two biggest gripes have been the poor lighting issue (which you've seem to bypass) and the slow processing, other than that it's been a fantastic camera! Here's my favorite shot I've taken with it.

Thats a great image,what jpeg settings are you using IE vivid ? and what have you got the sharpening ect set to
I think I have it set to the basic stuff, Standard Image control, no boost in sharpening etc. If I do any editing it's on the computer not through the camera. I tried using Vivid at one point but I really didn't like how it was not getting the colors right, so I try to set everything to the default camera settings (except noise reduction, which I have that on low).
