You need to hit confirm b122, you can get a lot out of the fact that b12 leaves you at -1(often times i do another b12 due to they're delay to react or I do an ex dbf2). It's also easy to do, last 2 can be done really late.
Also as you're probably aware, never blow all your meter on an xray unless its winning you the game.
Other things, use armor to end rounds you hit scorp with ex choke and he did nothing on wakeup, had you used armor thatd be an easy finisher. It's also a good xray bait, juking people by running up with armor and blocking especially against players like that works well.
Try doing ex dbf2 when coming out of tele, it tends to work well for me if people aren't expecting it, would of worked in your game for sure. That or ex choke works the same.
Also off f44 do something, whether it's armor, pursuit teleport, anything is better than standing there. I personally like tele to switch their inputs and it sets up a good ex dbf2. F44 is special cancelable remember that.
Learn some tick grabs too, d1, b2, jump in 42, and b1 are all god normals/strings that can get you really good tick grab setups. I've gotten a lot of mileage out of jump in 42 since it's too slow to use otherwise and super easy to tick grab into.
Also go into training mode and practice punishing low hitbox moves like slides. Would've save you a lot there.
Also jump in f2 sets up great punishes, if you can jump in and see you're hitting that's your go to max damage starter.
