20 second hand studies

Wow, these are really neat! I appreciate the style a lot. Very sharp! One thing I do notice is that the length of the strokes sometimes makes some of the anatomy look "pinched" if you know what I mean. So stuff kinda loses its form and proportionality you know? Some of the wrists and fingers are a bit off, I wonder if you could try blocking those shapes off more so they are apparent when you are sketching! 

Wicked stuff, keep it up. Very stylish!
