@Force_of_Nature some things, try not to do "66PP" as your primary range move, because I see that a lot, that's punishable. Striker was blowing that up a lot after your CH 2P's. 66P however is great, you only want 66PP when your 66P hit confirmed, not on block.
66P is -5 on block and +7 on neutral hit and covers a lot of distance, so you can use it as an offensive/defense range poke. You are also +12 after 2H+K so you do not need to back off.
You don't exactly seem to have her ranges down just yet, I would suggest the following;
I would
strongly advise learning how to use the H+K, that is Momiji's best single poke, hands down. H+K can create an offensive/defensive wall when you put it out there at good ranges, forcing opponents to figure out some way to get around it. It creates an objective for them and you can then start using other moves to throw them off guard. H+K is always to be respected since it is fast at i12 frames and has a damage base of 28, and tracks (also range safe).
H+K, 2K, 2H+K, 3K and 66P are the five moves that allow Momiji to smother her opponents at optimal ranges like a wet blanket. Learn to master them because these make it difficult to approach this character, H+K being the best one.
Also, not sure if that was an error or not but using 214P+K as some kind of range move is asking to get punished.
