I can do canvases but I prefer to use canvas board as canvases tend to be wobbly in the middle (Hard to draw on).
Prussian Blue Hue
Yellow, Orange, Red and Green don't work, they're really weak colours and you can still see the pencil lines underneath. I once did an Heath Ledger in green...ugh...I think I burnt it.
Photo used is best if it has a light background (preferably white).
I usually do them in 5-10 gradient (any more and I'm going cross-eyed and the colours are hard to distinguish from each other).
This Tegan and Sara one was supposed to be 9 colours but someone saw it and liked it just as two and bought it like this.
