Hi iGoose, thanks for posting! These are cool shots (I like how even though you used flash you preserved the ambient light from the board and laptop). The "strobe" effect on the moving hand is a lucky accident.
That said, the problem with using flash is the subject is well-exposed, but the background is always lost, creating an artificial sense of the scene. My personal preference is to do something to lighten up the background to create depth.
I took a couple of your shots and applied a couple of Topaz plugins
, mainly Adjust and BW Effects. Adjust can do everything from applying subtle tonal fixes to totally reinterpreting the image. I made one image a bit gritty with exaggerated colors while the other is opened up and sharpened/softened at the same time, if that makes sense.
I hope this is what you were looking for (ideas and options), since your originals didn't seem to be post-processed yet.
PS: Because we are working with web-sized JPEGs, there is artifacting present which you wouldn't get with your originals. I just tried Topaz DeJPEG as a test and it reduces the problem (for those cases where lo-res is all you have).
