Alrighty, after some observation, I'd have to concur with Osi.
Before the advice, I'd like to to comment on the nice re-entry @ 1:08, using the momentum and a Falcon Punch to guard yourself. The only possibility with this not working would be a human player anticipating or reacting and running behind you to punish as the Punch finishes its frames.
Sliding U-smashes out of a dash can leave you open many times, as well as a blocked or spot dodged Sidesmash. Jab to Grab still works amazingly, and can lead into grab combos or setting your defenses up, giving you time to space yourself from your opponent.
Other than that, take Osi's advice on your recoveries, try dropping from a ledge and wall jumping to fake your opponent out, or drop and do a hop up onto the ledge with a U-air or Knee.
Score: 4-5 out of 10 (I can only rate you half because of the CPU opponent, play style changes dramatically with a human behind the other controller, and can affect game play drastically. If you can get any other matches up, I'd be happy to rate them.)
