Here's some stuff I drew for school. Click on a picture to see a bigger version of it.

Self Portrait (Graphite)

I don't like the source image for this one but the drawing itself is pretty good. (in my opinion it's better to use a mirror when doing self-portraits instead of taking a picture)

Mirror (Charcoal)

Used a generic source image.

The Jungle (Colored Pencil)

(my name is "Ilya")

Guardian Angel (Pastel)

From a source image. This took a lot less time than I thought it would.

Physical Constants of the Universe Unite! (Colored Pencil)

No source images used.

Tourist (Colored Pencil)

No source images used either.
