You and the light must be one with eachother, It's quite amazing how perfectly lit it is to catch each little hair, wrinkle, and even the guy on the bottom's eyes! Congrats on a funny and well composed picture!
Another great shot, with difficult lighting. Good composition. It doesn't look like the male is having any fun to me. With fill flash, how far were you from the subjects? Were there any accessories on the flash itself to reach that far? Good job!
