Thanks for your nice designs. I can't believe that you managed to get a W and C into the symbol and not suggest a british bathroom (WC). That is amazing. It actually looks really interesting and arresting as well. I think the fade on #51 and #66 towards the top of the symbol is a little too strong - the letters fade out too much in smaller versions.
You were by far the most successful in pursuing a monogram design. I also like your font in #121, #122, #66 - more distinctive than most with the little subtle tail on the R.
