Hi Ray!
I have to say i quite liked the video. you seem to have the commentary down to a T. but my only piece of advice would be "Less is More". Your appear to be quite skilled at editing but don't let that go to your head. Try to keep editing to a minimum. over editing videos can ruin them and you have some really good content, i wouldn't want you to ruin it by having some sort of edit every 5 seconds. jump cuts are fine but when it comes to cutting out of the gameplay, try to keep that to a minimum if you have to use it. Also the titles you used, like the "walking" and "sitting simulator" titles at the start of the vid looked a bit amateur, try and change the font and colour to make it look more professional. apart from that your doing well man!
hope i could help
