Against Snake, you shouldn't be using Fthrow so consistently. It doesn't give you any benefit at all. You can't follow up with anything and it just resets the situation. Instead, use Uthrow for juggling Uairs or Dthrow for damage. I also see you don't use Dtilt at all for the most part. That's one of the best tools to combat Snake. Also, don't end the Dancing Blade combo with GDB4 unless you need to Shield poke with mind games. RDB4 is much more reliable as it can't be SDI'd and you will most likely knock them off stage.
Those are what I have to add for the Snake match up any how.
Edit: For Wolf, just some quick notes. For the Fthrow to FSmash, I believe you need to stutter step to nail it, hence why you missed. During the first stock, you could have had a lead if you went for the Fthrow to Dair. I believe you can CG Wolf, so it should have worked. I don't remember which jump is required and I'm too lazy to look. Also, Uthrow again would have helped you more this round than Fthrow. Oh, and if you break a shield and go for a Shield Breaker, space it better. That Wolf could have potentially lived if he was smart and used DI and an aerial, which would have obviously wasted your shield break. Spaced properly the Shield Breaker kills at something like 20% sooner than usual.
