Thanks!
Do you mean kind of like the death sequence in Starbound?
if you dont know what im talking about nevermind
ill try that
Well, sort of...
I mean, I haven't been doing pixel art for very long, so if any veterans want to correct me, go ahead. This is just how I do it:

This is my Deadpool drawing from earlier, thankfully I still had the skeleton saved (:
To stop me from drawing weird limbs that go all wonky, I draw up a skeleton like this.
From there, I just expand out the limbs/torso/head and colour it in.
I find it easier if you draw the torso first, then legs. That way, you can better scale the arms.
Hope it helps!
