can someone give me advice on this build here ? (PF)

[Nosta]

Can I get some people to look over my build and help me improve it with changing the race or classes?

Race- Oni Spawn
Class 1: Titan mauler (1 LV)
Class 2: Mutation Warrior (4 - 20 LV) (Current character level 5th)

Stats STR 20 DEX 14 CON 10 INT 10 WIS 12 CHA 12

Background Trait
1: Accelerated drinker
2: Iron liver (Mostly for the Boost to drink boozes)

Feats
1; Monstrous Mask
2: EWP Butchering Ax
3: Skill Focus Intimate
3: Intimating Prowess
5: Signature skill (Intimate )
5: Power attack

future Feats
6: Cornugon Smash
7: Not sure
8: Not sure
9: Not sure

The idea of this build is to Boost my intimidate with stuff like rage and mutagens and enlarge person potions using my tail and Accelerated Drinker to down this as quick as i can

Ok I see a mistake i made it

should be 2 level Titan mauler / rest mutation Warrior

I am now not sure of my feats though

Still plan to wield the butchering ax and i want signature skill

but not sure what a good line of feats would be

Is this a player build or monster build ?

Oni-Spawn is a Tiefling, for anybody not familiar with it and wondering.
