It's not that I'm bashing you because if I could I would set up a mat anywhere possible, but you need to move that shit into the back yard or something, trust me rolling in the living room is bad news. You should take a few more classes before you start rolling at home, When you're more comfortable with it theirs a lower risk of injury especially if you're going to be doing knee bars.
as far as critiquing you, you're doing well for just starting out(more in depth stuff has already been posted) but it'll be quite a while before you really need other people to help to get better, just go to the gym as often as possible, train as much as you can, then ask us to critique the video of you winning your first tournament. :icon_chee
