If that's freehand you have a very steady hand!! Great job. Will you color fill the graphic to darken it up? Don't forget to use a good spar varnish if it's going to be outside in the sun. If you don't the sun will fade the sign in no time.
I want to fill the graphic with probably black but must wait to see what the customer wants. I usually put several coats of varnish on my signs, with a few coats of danish oil as an undercoat works well here where sunshine is not usually a problem.
