Aw, thanks so much!
No guidelines for me! I usually do this really rough sketch first and then just make another one over it, that's why it's so messy
Like these are my first rough sketches.
That's where I get problems with proportions though, the legs are usually on a shorter side than they should be and the characters are frequently around 6.5 heads tall.
When it comes to line art I most frequently rework the sketch to be better proportioned, buuuut I don't want to lose the fluency of the line and process when sketching and any kind of "building" is killing it immediately for me ^^
I just start from the head (mostly face) and then work places! You can see I redraw a lot to get a feeling what goes where, it's hardly a strategic planning
