Party shot

A photo I took during my first ever big party (hosted by one of the fraternities of the Medical School I'm enrolled in).
Taken with a Samsung Galaxy digital camera on Auto mode.

Whatever made this look nice, it was purely accidental. I was hoping to take a shot of the crowd and the people dancing on the space in front of the stage and DJ booth and all I had was my height, my arms extended waaay above my head, and the the standard (read: "noob") settings on my camera, haha.

I didn't expect to like how it turned out, with the silhouettes, the party lights, and a decent amount of the white light diffusing at the center. (feeling so pro without an SLR, yo! XD)

Comments are welcome regarding the composition, lighting, etc., haha. Seriously! I mean I like how the shot came out but I know it doesn't mean it's a good one
I am also open to suggestions on how to take better photos like these, such as which modes and settings I should probably look into, etc. so I can perhaps depend less on lucky accidents to get better photos at these events, haha!

**Night events and dark room-type events
Thanks in advance!
