Ohmygod I relate to all of those points X33 I feel you bro

Of course I do weird things when I draw I do it most of the time

2,3,4,5, and 6 are all definitely me

I have a habbit of starting sketches, but not finishing them. Kinda' likeyour hing with the music, I don't want to work on a sketch unless I'm feeling the same mood that is being portrayed.

Lol I definitely do the second one and third one. And I definitely don’t sleep some nights so heck sleep!

If I'm drawing a face I always make the same face that the character is making. Some of my irl friends said that they look at a mirror, but I just need to feel the same thing the character feels
I don't do that (along with a lot of things on this list, sorry) but I understand completely. Generally music is the thing that does that for me though.

*I need to listen to music that will set the mood otherwise I'll delete the scetch and draw something that matches up with the song. It's a horrible habit of mine that I need to get over. *
As I said, I do the same thing, but not to the point where I need it to be super perfect or I'll delete it. So you should definitely get over that. Stop erasing sketches, just let it be my dude. You are going to have drawings you don't like in order to get better ones afterward. Just gotta accept that. Nothing wrong with re-doing sketches but to be honest I usually go with my first sketch lmao, no matter how bad it looks. Even if it's a commission. As long as I don't neglect it because I don't like the sketch and I put effort into it anyway I'll be happy with it.

I will not get up from drawing unless I'm thirsty, hungry or my dogs are hungry anything else can wait.
Honestly same. I might take a break for dinner though.

screw sleep!
^ Preach it ^

*I keep dropping my tablet pen! *
I don't really drop mine very often but my workspace is a pigsty so I lose it on a monthly basis more times than I can count on my fingers and toes..

As for my own weird habits..

I ted to procrastinate at random??
On one character I will skip sleep in order to finish the drawing immediately no breaks for anything whatsoever, and then on another character I'll get a sketch done and procrastinate for weeks, sometimes so long I give up. And the character could have such a simple design and I'd still do it!!
