This is a model train enthusiast's room. The area to be worked with is a 20' long x 21" vertical section that changes to a 43" section of the ceiling at a 45° angle. The wall is already painted a sky blue color. I would like a sky scene ( clouds ) with a sunset. This must be painted in a 1:48 / 1:50th scale size. That is the modeling size being utilized. The work area is free of any obstructions. I am up against a time schedule and would appreciate a timely completion of the job. I reside in the area of Magnolia Delaware. U.S.A Thank you for your time.
