Bird of pray

A new charcoal drawing I did, this time no more compressed though, used up most of it with the last ones, and wanted to try the natural one instead, i've had a couple of pieces for a while, a new pack actually from a dear friend. The drawing was done after a refference photo which I cannot scann yer unfortynately, but that's that... exercising my charcoal skills still...

P.S. Caution with natural charcoal, it stretches like hell if you accidently wipe your hand across the paper.
