Seeing as noone else is giving any real C+C I guess i'll have a bit of input...
Your lighting is quite good. As a fill flash in the first it works (and would look good to the untrained eye), although in the second it's starting to get a bit obvious you're using some sort of external lighting, due to the shadows in unnatural places. I'd recommend a reflector and/or diffuser with your flash to even up shadows and give a more "natural" look.
One last thing, perhaps this would fit better in the People forum...? He is glamorous, but..not..that glamorous...
