Okay, just some things I would say:

There is not much that I would criticize from what I've seen in your fights. You aren't going to rush down on your opponent and wait for a moment were you can land a counter-hit. That's how you have to play Kasumi if you don't want to get punished a lot. Your poking and the usage of it's delays looks very good too. I like how you use 4H+K, just mix it up a bit more with high attacks/mid punches, because you are relying a lot on mid kicks in general. Sometimes, you missed some damage from juggles, (e.g. in the first video at 0:35 and in the second one at 1:40) but I'm sure you will get it fast with playing a bit more.

I'm not sure how serious you want to take 1 bar matches, but some things I would recommend are:
Starting a match with 1PP is not a good option in my opinion, your opponent can easily punish you if he decides just to block (referring to frame data offline) or you could get counter-hit from a fast mid punch many players like to use right at the beginning. I also wouldn't use the sidestep kick, it's to unsafe if it get's blocked, especially not against Hitomi because she has a lot of tracking moves that will catch you anyway.
I wouldn't use 33P after 4H+K. Even if the latter one hits, 33P can be avoided by stagger-escaping and you end up back turned. It is also very slow. If 4H+K hits, 4P is guaranteed, so you might better use this.
Just remember that the H+K 2K 6P+K combo for critical burst is not guaranteed. It can be stagger escaped easily. It may work online on opponents that do not SE or don't know that, but if you are facing a experienced player offline, you surely won't be able to land it that much. Better use the guaranteed 9K option after landing a H+K turnaround stun successful.
Your poking looks quite ok, just don't rely to much on mid punches. Hitomi is also very dangerous in this case, because she has a punch parry against high or mid punches. Your opponent in the video here was not a beast with Hitomi, but if you play against an experienced one, you might notice this. Your juggles are also good, but there are some that deal more damage against lightweights, so you might take a look at the combo threads for getting even more effective.
That's what I would say, I hope it is helpfull for you guys
