pastel pencils

I'm starting a series of this bear in multiple media. He's a wood carving I bought in Bath, England in 1994.

This image is with 5 colors of pastel pencil in the Hand Book Artist Journal (great paper!). The colors are green, blue, yellow, ochre, red.

I put a little w/c in on top of the background red, just to fill the spaces.

I love the intensity of pastel colors, the simplicity of use, but (have I said this before?) I hate the dust. Does every medium have one significant quality to dislike?
