Thanks for the kind comments.
The pictures come off of the camera rather dull, but I cut out the subject(s) with magnetic lasso and use high pass filter and unsharp mask to sharpen them, then I adjust the color cast of the background and the subjects seperately to enhance the color and contrast (the on-camera white balance just never quite seems to get it 'right').
With ISO over 800 on the K10D, you pick up a lot of noise, especially in the under exposed regions of the photos.... so I usually contrast the image a bit to try to lose some of the dark area noise by clipping it black... from there you just have to be careful not to go overboard w/ sharpening.
Here's a blow-up of #2... still not full size, but as large as flickr will allow me to post.
You can see there's a bit of motion blur in this one as well, 1/125s for this shot was just not quite enough.
