Once in a while I do a piece that I really like for one reason or another, and decide to share it with y'all. This is a tiny (4x6") portrait in watercolor pencil. Watercolor pencils are like regular colored pencils, except after you've drawn something, you can use a wet paintbrush to move the pigment around, until it looks like a painting instead of a drawing.
It must be really difficult to get the painting right with watercolor pencil and lot of work too. I'd imagine you would have to be really good at sketching first to be able to get the contours right for portrait painting(Erasing wouldn't be an option, I guess, as it would leave a scar)? Else, you end up drawing someone else altogether. Watercolor pencils,usually, I believe are used to draw lips, eyes etc. but it would take a lot of smudging to draw backgrounds like the blue tint in your picture.
