Ginga School Artwork

This is an artwork I did as a school project in the Helsinki Senior Secondary School of Visual Arts.
The idea was to use pastel chalk (can't remember which) in a straightforward way.
The real size of this is actually A2 so couldn't use my scanner and had to take a photo of it (that's why it's a bit slanting and out of focus).
Over all I got 10 from it (mostly technique) *surprised* I didn't think it was that succesful.
And the subject is from a '80 anime called Ginga Nagareboshi Gin.
