I'm just gonna make note of things I see that you could improve on/straight up fix for your Filia & Double. I don't play Painwheel so I can't help there.
General:
-I don't believe your pressure is linear, so more as you are leaving too many opportunities to get pressure on the table. Any monkey can run a simple high-low-throw mixup once you get pressure, it's just a matter of recognising situations where you can take that advantage.
-At neutral, you need to focus more on making your opponent block shit. Sometimes when you're being overcautious, you're leaving opportunities to make the opponent block right on the table.
-You need better punishes, especially meterless punishes. Specifically, to be more aware of what can be punished and to act on that information. You're letting gllt get away with murder whenever he does something like whiff Showstopper and you don't kill him for it. -Some things, like cerebella's overhead from her run, are punishable if you DON'T pushblock them. It might be hard to confirm but it's worth it if you can see it and don't pushblock it, that way cerebella dies.
-If you can punish something with a guaranteed throw(7 frame), then you can punish it with a jab(6 frame generally?). Jab punishes will lead to bigger damage combos, so try not to punish with throws if you can help it.
-If you're punishing something like a blocked Diamond Dynamo, punish with either your Heavy launcher, or jump->falling heavy normal->heavy launcher. The damage adds up.
-If you're not going to kill with your combo, it's optimal to attempt a reset instead. That way, the opponent has to guess a mixup, and if you succeed then they take more damage than they would've if you just let the combo end.
-You need to be aware of where you can push buttons to take the initiative. If they're doing wack pressure that results in you not having to actually block anything for 5 seconds then you can make them block some shit then go in.
Filia:
-Consider using more IAD j.LK or j.HP to move, since just raw instant airdash moves you horizontal then drops you vertical. Using a normal lets you retain your momentum, lowers your overall air time, increases horizontal distance travels, and threatens space. You can't block during airdash anyway so you're not really losing anything here.
-Consider using more LK Airball to move around as well, since you get to airdash and do air normals after, as well as regular jump->LK Airball->Airdash forward->Call assist ontop of the opponent is a good way to get in. You've been doing too much LK Airball, airdash backwards. That undoes your work of closing the gap with LK Airball in the first place.
-After OTGing with c.LK s.HP, just do j.MK(1) qcb HK, or j.LK/j.LP j.MK(1) qcb HK to pick up. You're dropping that combo way too much and consistency is more important than one or two hits of damage.
-I don't know if you're doing it intentionally to get the tech chase, but don't do j.HP adf j.LP j.HK after you OTG someone from Gregor or an assist. It's better to go into the j.MK qcb HK etc part so that you can get the restand to either finish the combo or lead into another reset.
-Filia vs. Parasoul. Parasoul has the capacity to keep you out, but Filia is much faster than Parasoul. If you see Parasoul whiff an air normal in IAD range and doesn't have assist available to keep it safe, or isn't calling assist, then fucking IAD j.HP in and maul her.
-Stop backing off when you're at mid screen so much. Your job as filia is to rush that shit down and close space. Giving the opponent space is the exact opposite of her game plan. It has its place if you want to bait certain things like assists but for the most part, rush that shit down.
Double:
-More air throws, and air throw resets. Double's air throw game is quite good due to ease of conversion, and since she can do air throw/burst baits that lead into themselves. Doing air throw with double on your opponent's incoming is a good idea if they don't have any air supers(ie Cerebella, Double, Paraosul), since they have to tech it or get thrown if you do it meaty. If you get them used to expecting air throw, then mix it up with meaty hits or gross crossup incoming mixups or whatever since they're stuck in throw animation.
-Your burst bait doesn't work because you're not giving gllt a reason to push buttons. Air throw him in the same situation more, THEN start burst baiting since he'll be pressing throw tech.
-More left-right resets with assist+flesh step. It's gross.
-I would have more things to say but I am not good at double
