Obi von Knobi`s Fresh Sketchbook

[Obi von Knobi]

I`ve finally started to draw "for real", not just once in a while like before. So I made a SB to get critique and to get better. Isn`t that what we all want? Here`s some recent paintings. The face is not done yet (as you can see) I have a little trouble with the skin tones... Any tips?

I'ts been a long time since I last posted. Meanwhile I've done some pencil sketches which I will post as soon as I get to a scanner. I've recently started Uberman's Sleep Schedule (http://www.google.no/search?hl=no&safe=off&client=opera&rls=en&hs=Eey&q=uberman%27s+sleep+schedule&btnG=S%C3%B8k&meta=&aq=f&oq=) which means that I only sleep 2 hours per 24. This way I will get much more time to draw. Heres something I did today, the first digital since January 2009! It's not done yet as you can see. What can I improve? (Except the background obviously).
