Reply to First set played in front of an audience, tell me what you think! Tips appreciated

A few months ago i got 30 minutes of playtime at a local club. I decided to make the most out of the time i got, so i put together a mix with the aim to fill it with a wide variety of songs but still keep some sort of flow.

Tell me what you believe was good/bad and different things i need to work on! Help is very much appreciated.

I'm off to work very soon, if anyone wants the songlist i can fix that when i get back (in a few hours).
