My last for a while :(

Here are some photographs from the night my camera stopped working. Taken at my friend's church's performance thing.
#1
#2
I was seated in the second last row, so had to zoom in - though I would have prefered to be up the front taking photos
Tell me what you think, it's not that I can shoot the same pictures again, but maybe some things to remember for next time.
Thanks!
(oh, and about my camera not working...
the autofocus stopped working, it would continually hunt. I thought it was the lens, until I changed lens and it continued being unable to lock focus.
When I got home, I took the lens off and lifted up the mirror and saw that the secondary mirror was stuck directly under the mirror - explaining why the autofocus didn't work. So I unstuck the mirror and thought all was fine, but then after that, all the pictures came out 1/3 black, as the secondary mirror would not lift then the main mirror lifted and shutter opened. Someone showed me some DIY fix guides online, but I'm a bit scared, brought it to Canon and they said it'll take 4 weeks, and to get a quote will cost $50. I'm planning to get it fixed when I go to Singapore, since if I can't use it in the next 4 weeks anyway, then it's exam time (not much time to take photographs), then I'm off. I'm also having thoughts of getting another DSLR)
