I've not played PoP:WW but from a browse of the soundtrack you definitely captured the mood really well, and it was generally pleasing to listen to.
I would have perhaps liked the drums to be a bit more prominent in the mix, particuarly in the latter stages of the track - a punchier kick in particular would have helped build up into the ending riff. I know this can be tricky with some VSTs but if you don't mind dropping some $$ GetGood Drums is a really good-sounding and easy to mix kit for rock and metal.
