New player Switching Characters.

Any Advice on learning a new character after maining another for an extended period of time. I am still faitly new to Fighting games and tekken.

I was maining lars, got him to Raijin around the time Eddy came out but i got burned out and bored of grinding ranked with him. It was a mixture of only playing ranked and i think his move set is to simple for me personally.

Recently got back into the game because my friend convinced me to. I have been playing alot of Lili since she feels like a more complete character.

My issue is my entire perception of this game is threw Lars's eyes from Punishment to combo structure and everything else so i find myself in alot of situations where i did the right things with the wrong character. How do i fix that and potentially play more than one character more seamlessly.
