15. How long does an average piece take you to complete?

Hmm… it depends how detailed the picture is. Something like this:

Would take a couple of hours to draw in pencil, then maybe another hour for outlining, scanning and colouring.

Whereas something simple like this:

Could be completely finished in one hour.

On average though maybe about two hours for the whole thing. Often I don’t do it all in one go – I do the drawing in one sitting, then outlining and colouring later, even on a different day.
