There are exceptions, of course, like Darth Sidious- but let's be honest here, he'd really be better off with a mask.
Also, in reference to this morning's post- you can probably see what I mean about there not being too much here to lose. If that were the only issue, I probably wouldn't have even said anything about it, honestly. It was my first time trying this white-details-on-black drawing style though, and I think it turned out fairly well!
