I haven't tried out T6 Law for myself, but I have a few ideas off the top of my head.
If you're picking up Law, make sure to learn DSS (Dragon Stance Shift...I think). I think regular Dragon Stance (DS) is entered doing d1+2. So basically you can buffer DS off your moves. The really weird thing is you don't buffer it by doing d1+2, but by b,f. So a starter is b234 (buffer b,f,b,f during the animation), DS 3. So it'll look like b234 into DS 3. I do the buffering fast so I make sure I get the transition, but I think you only need to time it near the end of the b234 animation. I think for execution-ease sake it's b,f,b,f for buffering after kick moves and b,f after punch moves so punch moves are a little easier to buffer.
Also, try using his FC d, df, d, [df] 3 for a really quick low and do wakeup kick 3 afterward for additional dmg. I'm guessing his bound is now f1+2 so maybe afterwards a simple option is ff213.
Use his ff3+4 double break throw and it can combo afterwards. Sorry, I'm not too familiar with him, and some may be iffy since I only know this from T5DR but those are some basics to start off with.
