Ok big man, as a first PA this is ok.

I`m not a big fan of ableton PA`s cos they sound like DJ sets most of the time, and most people don`t really push the software for what it can do, so they are essentially digital DJ sets, rather than live PA`s, so forgive me for being a bit tough (as if you`d expect anything else from me though right?)

Overall the energy of this PA dropped out after 15 mins. By that I mean that there was no rising and falling, just the same level of intensity all the way through. So maybe beter track selection or more variation would help.
Also, some of the tracks just looped on, doing nothing for too long. Seeing as your not having to tweak vinyl, you have plenty of time to make things interesting with all the lovely tricks, and really need to do more than fading parts in and out.
It also might help if you listen to a lot of mixes to pick up on some of the mixing techniques used in techno, as you don`t mix vinyl, these would be handy for you.
There are some good tracks in here, but overall they are DJ tools, and really need to be worked and chopped etc to keep interest.
Well, now you have caught the ableton bug, keep at it dude, practice practice practice.
