Red Sofa No.2, 10 x 24 (?), oil on linen
Here's an example of what not to do. See the top of the sofa intersecting the figure right at the neck, separating the head from the body? (And the sofa is blood red! Yikes!) When you encounter an awkward alignment like this, just move the line up or down a little.
Theoretically, one could pull off a composition with odd tangents by manipulating edges and contrasts and what not, but sometimes it's just easier and more effective to simply move the offending element.
Otherwise I like this little sketch. I was especially happy with the brushwork. Too bad suggestion of decapitations don't quite fit into my repertoire.
