I'll tell you one thing first off, never worry about your style looking like someone else's. That way lies madness. Draw in a way that feels natural and good for you.
Also, take it from someone who has never had a quiet brain. I'm 23 years old and have the dual anxiety/depression disorder and I'll tell you, it can be a ride. Your info says you're 18 so I'll tell you this, it took me until a year ago to really accept what I have and what I am and what I draw in response to that.
(much of my art pertaining to my disorder is not on this site yet)
Just tell people the truth. (easier said than done) Just tell them that you feel like you have to ask certain questions even if you feel they're useless or baseless.
We're all in this ocean together, we'd better get rowing.
Anyway, onto the art. You've got a dope-ass style and your use of color is awesome. I friggin' love the segmenting of this dude's arms and the little bones sticking out. Hella yeah. That octopus too. Bomb ass stuff.
I see you aren't too much of a background person. Eh, neither am I. Can't fault you for that.
Keep on keepin' on, my friend. Life only gets more lively from here.
