I'll give you some real simple advice that can do you worlds of good :
DON'T STAND STILL SO MUCH (caps i know...) but seriously you need to be alot more mobile -- mu's can benefit greatly but mobility and its a great way to get used to doing crossunders/overs. Keep moving -- do fake outs/ high jump/dash jumps over your enemy -- just dont move (or stand there) mindlessly through the match
I am a 6C junkie and I notice a few times you land a 6c on block then let mu's animations continue .... that's a big no no.... anytime you land 6c on block -- use that opportunity to place a stein or if your gutsy an Origins (DP) -- if you feel they will rush up and counter your ass.
Another easily change-able habit I see you have is that you often like the start Totsuka while right above the ground... I see in your video that getting punished all the time. stop that!! *smack* -- if your going to do an air Totsuka then jump way ass high so they have a harder time getting to you before your laser finds them (just not mindlessly please).
Do yourself a favor and stop placing steins while very close to your opponent (while you can do that - its a bit more advanced and you gotta watch your opponent carefully) ------> http://youtu.be/r8i6DZbCu4M?t=7m22s (bad bad!! don't do that)
Another thing --- stop mashing out recoveries and trying to always land a J.C or J.2C on your (quite mobile Tsubaki) opponent -- instead just retreat, get away and clear your head. ( DONT do this anymore! ----> http://youtu.be/1ZUqw9ufQVU?t=2m14s ) its actually alil painful to watch but cram that exp into your head
