Start of a digital inking practice piece over a pencil by John Byrne:
Hmm, looks like you need to steady your hand a bit. Moving from the shoulder and elbow (and not the wrist) is a good way to keep lines from getting messy. You should also think about line weight since your figure is getting lost in the background.
Most of the drawing programs are going to have some way to make the geometrically straight lines on things like the dresser be perfectly straight (e.g. Photoshop or Gimp touch one end of the line and then hold down shift while touching the other end of the line). Nailing the straightness of those lines on the furnishings might provide some contrast with the more fluid lines on the figure.
I could see a figure, but I couldn't tell for sure if it had an alien head or something and it took some concentration to figure out it looks like a woman is holding a mirror in front of her face or something. I would do a little more work there because everybody will naturally look there. You want to make sure they can see what they are supposed to see when they look there.
