Not bad. Good title.I think you guys still have a bit farther to go before making a combo video, although some clips were keepers. Video editing was pretty good.
Ok, suggestions:
1) Use fadeout sparingly; it's much better just to use normal fade. It just flows better, and it's nicer visually.
2) Save some of those good clips and keep playing, then when you've got a bunch of clips that are awesome, it's the right time to make another combo video.
3) Although the music was awesome, it became a little unexciting after 6 minutes of the same song. Next time you should choose a good place in the song to fade into another one. Music is one thing that really sets a combo video apart from rest. Timing and artistic choices will make things awesome, even with video games, so keep that in mind.
4) Any chance you could make the peni s scene a bit shorter? (omg, ***** is a curse word? WTF?)
Overall:
Not bad playing; very good at points. Keep in mind the details of video editing, try to make it as exciting and captivating as possible. Anyway, keep it up. I hope you take my advice and make another video later on.
