My N800 vs. my "Notepad 800"

Here are two sketches done of the same shell, 20 minutes apart from one another. The n800's was done first. The light is natural i.e. from the sun coming in from the window; although, for the second sketch, done with the notepad, the lighting was better. Hence the further I got with the n800's sketch the darker I made it because at the time, it was.

I plan on doing some more of these. I am going to stay with black and white, relatively, and try working on comparisons of sketches from life.

note: the n800 sketch was done in MyPaint and I found that, as Uniquie311 had found before, the left side of the tablet was relatively unresponsive. I am going to post in the MyPaint thread about this problem.

note 2: The paper sketch is a photo, not a proper scan, that mid tone wash is not the color of the paper or my doing, but I like it!
