Some things I noticed from the start, you jump wayyyyyyy too much, and barely walk at all, for now, try to jump as little as possible and basically only jump when the other person is knocked down or when trying to avoid a fireball. Which brings me to my next point, because you’re mostly jumping to get from one point to another, you basically have no form of neutral game whatsoever, a good way to read up on that is this site http://sonichurricane.com/?page_id=1702, basically the ultimate footsies guide, chapter 5 also handles jumping.
Another thing I noticed is that you don’t really know her basic combos, I would check out one of the stickies that have them all listed, I think for now a good one to practice would be cr. lk, cr. lp, cr.mk xx (cancel) into shouoken, or cr. cr.lp cr.hp xx shouoken/EX tatsu, depending on range, and learn these two bnb punish combos, cl. st. (close standing) hp xx tatsu, cr.hp xx EX tatsu > otoshi/sweep/ultra1/ultra2, or cl. st. hp. xx tatsu, st. lk, xx EX tatsu > otoshi/sweep/ultra1/ultra2.
The latter combos can be a bit tricky at first, so if you cant do them 100% yet, you can always punish with something simpler like cl. st hp xx shouken/EX tatsu.
This also brings me to my next point, you’re wasting a ton of meter, one of the reasons being that you can’t connect a normal otoshi after EX tatsu, so you do EX otoshi instead, then somehow still whiff, but even in general, I notice you for example use cl. st. hp xx EX shouoken a lot, a much better option would be cl.st hp xx EX tatsu, otoshi/sweep if you want to spend the same amount of meter for more damage and a hard knockdown.
These were the main points I wanted to cover, hopefully this helps and in case I’ve missed something , I hope someone else will be willing to comment on that.
