In terms of future articles and so on. I think it would be awesome to talk about sketching in general.
What makes a good sketch? I know it is a personal thing and we all sketch in different ways, but some words about it, covering various aspects would be awesome.

Some ideas for this could be:

Paper quality, pencils and perhaps alternatives to pencils, like blue and red “animation” pencils.
How to draw lose and when to make a “commitment” to a stroke.
Can a sketch be used in a final painting / illustration other than to be a base for a clean line rendering?
What sketches are worth keeping, what can be trashed. Any system to store and use the sketches for future projects.

Everything regarding sketching would be awesome!
