CityArts Banner Full Scale Sketch

I've currently put all my other in-progress works aside in order to complete my banner/sign for the CityArts Cooperative.  I had planned on doing this sketch in paint yesterday but found that I had none and out of anxiousness, I went ahead and decided to just use good ol' Crayola markers.  Now that I am satisfied with even this rough and three tone sketch, I've gone ahead and purchased some paint and will begin to work on the final tomorrow.
