They look great. Honestly. I never would have guessed you picked up that light only a few hours before hand. I'm assuming you're working with it on camera which is cool. Off camera comes later
Right off the bat, it looks like you know what you're doing. (which is good because I don't know what I'm doing half the time! haha). I see no hard shadows which leads me t believe that you bounced the flash off the ceiling or wall. (I'm betting on wall, because I see some variations in the light gradient from side to side. Let me know if I'm right!
