Great pics. Sr. Frog is correct, a little too harsh on the lights, but not by much. Could be a post processing issue too. Did you increase the contrast during pp? I haven't looked at the histograms, but it seems like it would be an easy fix. I think you have a good eye for this type of photography.

Sorry to hear about your little one, I know it can be scary to have to go through this. But, you're in a good area for this kind of procedure, and if anyone in my family had to have this done, we would be in the DFW area in a heartbeat. Good luck.
