Alphabet Monogram

Ran across a series of alphabet monograms a couple years ago, (designed by Charles Demengeot in the late 1800's) and I've been meaning to try my hand at one ever since...

This is my first crack at it, so we'll consider it a WIP. It's definitely been an interesting / slightly frustrating experiment up to this point.
