My friend from max3d.pl forum started a awesome new idea for artists. He created "February Sketchbook Challenge", you can find the facebook group HERE. Main goal of this event is to make one sketchbook page per day through all February using whatever technique you want.
So lets get it started! This is my first page. It shows an ancient mech wizard on dead horse. :)
And for the end of post something inspiring from Leonardo :D !
