Eh, not really anything to this but screen pumps and changing to black and white for a few seconds, also I think your sync may have been off for a bit of it, but that might have just been some lag on my part. Although after looking at your channel this seems to be your first video (correct me if I'm wrong), and for a first video it's pretty decent, so well done on that.
Also, you might wanna do some spellchecking next time, I'm pretty sure it's spelt samurai.
