Not really much I can say about the Tager match-up. Your play-style was appropriate - keeping you distance and trying to catch him off guard - although I feel you could have been slightly more assertive; there's nothing wrong with trying to pseudo-zone Tager as Noel, but she is still a rushdown character so you'll have to find the right time to go in and deal some damage.
I think the same can be said for the Platinum match-up to a degree. While you didn't seem to respect (or fear) the Platinum player nearly as much as the Tager and consequently made more approaches, you didn't capitalise on the mistakes the Platinum made either due to poor hit-confirming or not knowing the best combos as pointed out in the list.
In general, I think what combos you do know were executed fairly well, but there were instances (specifically against Tager) where you slipped up and dropped a combo or just didn't follow up because you didn't think you'd the land the hit I'm assuming. I would suggest going through the combo thread which (although it is unfinished) has plenty for you to work with. Then once you're more confident with Noel's more advanced combos, you can move on to learning some blockstrings and mix-up which your game seemed to lacked.
