The Business. Now I'm seeing some problems like that arm that needs to be pulled out from the torso a bit. Might see if I can fix it. Really it was just a torso sketch though, working as usual lately on the serratus muscles and the abs especially.
About the lines - I drew these with some scribbling, but cleaned them up carefully. I think that's acceptable, though I'll continue to work toward always drawing cleaner to begin with. It's still true though -- when I'm unsure about what I'm drawing I scrub a bit.
