Software used: ArtRage 2.5
(a little bit of photoshop vignette, slight contrast adjustment and sharpen)

After having made some still lifes based on real reference I decided to make a quick freehand doodle to see if I had learned something already. Except a bit of contrast revelation and some general color behavior I must say I havn't learned too much, yet, except that it's so much more fun for me to just doodle away. On this one I've looked at some anatomy, but other than that it's without reference, which explains the inconsistent lighting and other weaknesses, but hey... I had a blast.
