Is this a decent Dual Wield build?

So after spending days deciding on a build I finally decided on one that I'm going to stick to. However I have zero experience with pathfinder so I was wondering if what I came up with is decent.

I decided I wanted to do a dual wielding monk with 2 sai's however since this is my first playthrough ( Core difficulty with some edits) I'm unsure if id stay lawful the entire way through so I made a build to compensate. I just take 1 dip into monk for flurry of blows. 4 into knife master and finish the rest of the lvl's with Mutation Warrior.

When it comes to mythic Paths idk I was just gonna wing as I didn't Want to totally spoil myself looking them up on my first run. For feats I'm just kinda gonna wing those after taking the standard ones for 2 weapon fighting.

for stats and race Dhamir for flavor. 16 strength, 18 dexerity, 10 con, 10 int, 16 wisdom , 7 char
