Foorame Inverted

First off, this is the version of the drawing as it was originally scanned (later I will upload a touched-up version), it was not altered in any way from a default scan.

This was a practice for me to break my mind out of the typical way of doing a line drawing. Basically, instead of inking lines, I outlined the lines and filled in whatever should be white with black marker. this was done a long time ago, and i remember this process being incredibly tedious and time-consuming. Its a wonder why I haven't tried again to do something of this nature? (look close at a few places and you can tell where I messed up once or twice! lol)
