ok few things
☼ too much dair, you only got punished a few times, but most players will get you a lot more with it. EVERY gw player probably dairs too much whether they like to admit it or not, especially when they are nervous. Its just something you need to make a conscious effort to try and reduce so when your playing someone better you don't get destroyed for it. That said a good time to dair, that you didn't, is when mk knocks you above him at high to mid percents, once he did and got an up b off. You should just get into the habit of doing a slowfalled dair to cover yourself. Also slowfall when you want to hit someone and see that you won't, to avoid punishment maybe.
☼ bucket brake! very important. Now you only died once, and your probably thinking 'but i died so fast it wouldn't have helped'. yes thats true, not this match, but i saw that you airdodged before you died so you gotta drop that habit.
☼ way more up air. i use this to piss off just about everyone i play, and it works on everyone, including good players. Some characters are affected more than others like, snake and ddd etc. But mk can find himself in trouble at times too
☼ dash attack the drill, it works.
☼ try to work more grabs into your game. most gw's don't grab enough, simply because gw is so disjointed you never find yourself that close. I will sometimes hop around and do empty shorthops near them w/ air dodges to get around them and grab. When you do start grabbing more, mix up dthrows and up throws to keep them on they're toes.
pretty good otherwise, but your opponent does need work as mentioned above.
