This is a drawing of me drawing myself while I'm drawing myself UNFINISHED. Comment on what looks bad, needs to be fixed, etc. In the arm, that's the shading from the tray on my lap. It's going to be erased once I finish the arm's outline and then reshaded to fit the arm. DA Link: http://the-whispy.deviantart.com/art/Self-Drawing-WIP-145927580
It looks really well done! Even if it is unfinished. As for comments on what to fix, it seems like on the tray's shading has a definitive line where the shading stops instead of fading into it. Idk, I don't want to comment on much because I know you'll be finishing it, but until then it is still really good as is imo.
The shape of the arm is really good, get that dark patch rubbed out and just leave a little bit of shading on the left side by your wrist. Also the line that cuts at the elbow should either be partially rubbed clean out, or faded quite strongly, nevertheless the impression that a line would belong there must remain, so don't remove the whole line.
As I said in the op, "In the arm, that's the shading from the tray on my lap. It's going to be erased once I finish the arm's outline and then reshaded to fit the arm."
