I found the 2nd half more entertaining, but then the credits appeared. :s
Why not the 1st half? Too many similar replays one after the other, it resulted in 'oh look another one' syndrome. The 2nd half however had more variety thus more interesting for me.
So critique... Transitions were a tad 'lacking', as much as I hate seeing effect spam a bit of variation is also good. No issues with the music choices, but you should try & mix the songs if you're using more than one rather than ending one song then starting another - it keeps the pace going and gives the video better flow.
All in all not bad, not great, although for a 1st video it's good.
