Beyond of Pluto

The Fourth Doctor in space....
He's beyond the "Pluto-(Charon)-System", for me it's currently the most interesting place in our solar system (you know, dwarf planet Pluto is very mysterious and it's very interesting for me since they've discovered two new moons - Nix and Hydra).
So, what else is there to write about the picture?

It's mixed (traditional) media:

the nebula was done with watercolors and liquid acrylic color.
The Doctor was done with acrylic colors (except the eyes - it's liquid acrylic color again).
Pluto, Charon, Nix and Hydra were done with oil pastels.
The background was done with acrylic color, glossy gel and "diamond glitter".

Phew, it wasn't easy to draw the Doctor's hair and to color the nebula.
