Wow, I did not even notice some of the flaws you mentioned until now.
Thanks for the advise, I’ll see what can I do with. 
especially the arm and torso.
Thanks for the comments guys.
I notice that a few people thinks that it doesn’t really look like Vakama.
That’s because I initially planed to make a random MOC with 2 “samurai” swords.
I called it Vakama (revamp) in the end after noticing that the way i use the mask and the disk launcher looks like that of the Toa Vakama set.
Right now I’m wondering if this MOC should be a revamped version of Vakama or a totally new character.
What do you guys think?
