Good shit, I really like the gas & bf1 stuff at the end!
2 things to note, some of those punishes are very range dependant, like Sindels b2 at tip range will make db4 whiff hard. And with her b2 being i13, it can be pretty difficult to judge your range react and react in time.
The other thing is you can FB u2 her f2 on reaction with enough practice. I would definitely recommend trying that out because it really cripples her ability to get her offense started.
