My first nightclub shots!

Hey guys,
Last week had my first gig at a nightclub taking some shots. tell me what you think and anything can improve on!

ALSO My biggest problem i found on the night was that not all of the ceiling was black so i couldnt bounce light, instead i had to point the flash directly at them which didnt turn out very nice, do you recomend a flash diffuser box?

Note. Pics taken from facebook so might quality isnt as nice as original

I liked the effects on 2 and 3

But I couldn't help noticing what an empty club it was.

Also a bounce card might help to keep things a little more portable but still diffused

Haha yeah was a pretty empty night..

Thanks for feedback, anyone elseeee?!
