sketch- hand studies 281111

I thought it might be good to draw some hands. I think the last time I drew hands alot was in year 12... about 6 years ago. I just wish I could draw hands without a reference.
Out of curiousity I wanted to draw a hand giving the finger, as I've never drawn it before. But I couldn't twist my arm around enough to get an accurate view... and I felt weird asking anyone to flip the bird at me for longer than a few seconds...
