True, i'm not good at drawing that much. Abd I don't post much either. But hope this is useful!

Ok lets start!

First of all. You need to draw a desk. (Its alright if it looks simple)

Draw a circle representing the head.

Draw a strait line down the middle. This will keep the blance of your drawing.

If your drawing 6 heads tall, put three lines apart about the size of the head. I personally like to free hand it but if you need more support to your drawings then draw two boxes, bottom a bit bigger than the one on top. 

Also, draw the neck a bit long. 

(Sorry for the size difference) draw the lower half of the upper body from where you drew the lines. Draw it a bit outwards.

Draw two circles then draw lines where you want your leg to go.

Draw a circle a the bottom of the line (where the desks legs almost ends). I like to make the feet a bit inwards but that's up to you.

Draw the hands how you like it. Also, draw the chair behind your character. That makes it more like their sitting. Like they aren't sitting on mid air right?

Draw the face. Ya can go to the other chapter where I talk about how to draw face looking a bit to the right and foward.

Erase the guide lines and touch up details. And you're done!!

I hope this was a bit helpful! Bye toots!
