From what I've seen I'll say that you don't use Flash real potential so far.
You almost never use his best string
b2, 2 which is godlike to get in so you're trying to fight with unsafe moves (charges) or shitty range strings (
2, 1) too often instead which makes your char even harder to play.
Also, you always go for the
d1, d2, d3 (very unsafe) or empty
d1, d2 whereas you could get a full combo with
d1, d2, ex-df1. This low starter will force your opponent to block
low and so eating a free
f2, 1 combo sooner or later.
Last thing : Flash
trait. You almost don't use it at all as well. I personnally just use it for decent BnB damage since you can get around 50% very easily. If the ex-df1 hits and I got it, I'll use it.
Thanks a lot sharing your game footage, you are the very first. I'm planning to do the same as soon as my injustice's fondamentals are good enough to get decent games.
