Lili is generally really easy to sidestep, it's just her crouchdash moves you need to be careful of since they center her tracking. Zafina has slightly better tracking but she's a lot more poke heavy anyways so it's not like you'll often be sidewalking big strings or anything.
You seem to be coming along really well. Not sure how long you've been playing overall but you seemed plenty solid. You fell for some of my setups (I'll detail them in a PM) but it's like... hmm, 60 characters to learn... yeah, you're gonna get hit by some shit! I kept getting creamed by your team because I don't know their moves hahaha. Game takes so much damn time, but I'll write you a PM and give you some tips on what to look out for.
I'm trying to get a bunch of games in this weekend since I actually have some time and NEC is next weekend. I'd like to not go 2-and-out but considering I haven't even fought half the cast yet, I probably will.
I only get to play a few hours every week or so, so I'm trying to make the most of them. If you wanna play shoot me a text, my number is PM'd to you. Definitely need practice against both of your characters!
Yeah, the amount of information to learn to be good in Tekken makes is frustrating at times. I've played Tekken for years, though only casually, I'm familiar with staple moves like the Laws' Backflips, Paul's hammer punches and elbows, Mishima's CD moves, etc. But there are characters I never really explored and some (e.g. Yoshimitsu) are different than their T5 incarnations (last Tekken I played prior to TTT2).
As for Lars and Jinpachi some general advice is:
Lars
-He's pretty well rounded with good combination of highs, mids and lows which help with his mixup game up close.
-He really doesn't have long strings, his approach is based on poking and punishing for big damage. 1,2_2,1; d/b+2,1; WS+2,1 are basically the most you'll see from him when pressuring, with the occasional f+1,2,3.
-His lows don't give him any advantage whatsoever (d/b+1) or are very punishable (d+1+2; d/b+4; f,f+4; f,f+3+4).
-The Screw Attack (u/f+3) is punishable on block. Though the animation makes it difficult to tell what exactly is it's maximum punisher; not even InaTekken has a definite frame number on it.
Besides my general lack of knowledge and experience with Tekken in a competitive level, I think Lars is best character at the moment. I just need to stop using u/f+3 as a panic button hoping to get a high crush.
Jinpachi
-Jinpachi just like Lars is all poking and punishing for big damage.
-Unlike Lars though, Jinpachi is for the most part very negative or punishable on block.
-Like Crathen said in the Jinpachi thread, he will be poking with his slow unsafe lows (d+3, d/b+2,1) until you start blocking/punishing them, to then threaten with powerful mids like u+4.
-I think one of the things to watch out for is his range. The guy is huge, and his legs can really reach from a distance.
-His mobility sucks. I'm no KBD expert, but backdashing with him is a PITA. At least he has Astral Projection, but that takes time to recover from.
-Also, and this is entirely my opinion, I think he is pretty bad at getting out from pressure. His st. 1 for some reason is pretty short, and his follow ups are either mediocre or plain bad: 1,2 is -17 on block and 1,b+2 is not a NC. d/b+1,2 is good against pitbull players, but it is NCc, so you risk a launcher if it didn't hit on CH.
Jinpachi is a character of respect and fear. If you respect him too much he'll beat you in no time.
