Pencil Drawing Timelapse

Hey guys, I did a pencil drawing timelapse. It goes for just over 2 minutes

Heres the drawing

Brief rundown.

I used prisma colour pencils. I hate using pencils, pencils hate me.

I found it hard to keep consistant and smooth. And I don’t think I am using them right. I am layerin with them, But it seems like the pencil will lift out some of the underlayer and it gave it a shitty, dirty look with random patches.

I felt I had to layer with them because 1) I dont really know what I’m doing, and 2) I found I hate to constantly go over and over it to get it smooth, otherwise it would be grainy.

Any advice using prismas would be appreciated.
