Sorry to be rude, but this a shit build.
You're lacking perception, you have way too much AG, Intelligence is too low, LK is ok. Bruiser and Heavy Handed are ok.
You need PE to see what you're going to hit, or else you're gonna bump into someone due to your low PE. I suggest 1 AG, you should be wearing Leather Jackets which have Sprinter perk (Lower your AG is, faster you run, so if you have low AP regen +, you can get away easily).
Now you can either invest it in charisma so you can get leader ship bonuses...dunno what you want to do.
You need higher INT so you can reach 250 HtH skill to get all melee weapon perks and yes, they help a lot.
My current build, just some random build. Not exactly the same as my waki sneak but just testing (and doing quite well)
