It's a cartoony character with a helmet (or maybe even a robot, who knows). Not a bloody anatomical analysis of a realistic human.

Oh, you... XD
I'll have to post some of my serious anatomy images to check how far have I advanced. This guy must be an academy professor.

What an ugly image. All the proportions are completely wrong!
The robot and human both have heads that are way too big. 0/5, wouldn't even look again.

Idk dude, when I draw I draw loose. Anatomy is just a guidance toward what you want to express. You could fine-art it toward the 100% correctness, but that just not my style.
As shown here.



I'm rough, what can I say. :P

Great stuff man, i've always found myself wondering how people can do both rough and good looking at the same time, but clearly it is possible. :v
The only constructive thing i can offer is that Spidey's eyes up there are misaligned and the lighting's kinda inconsistent (though you have to look closely to notice it), but there's nothing outright bad that i'd be like "FIX THIS OR I WILL MAINTAIN YOU PERCUSSIVELY" about. I've always enjoyed your art, today is no exception. ;o

I would post some anatomy drawings, but those are all naked girls, so can't. ;[]

Censure the naughty parts and show usbsime more magic

Ok, but, it kinda ruins the picture. Here is some classical pose.
