Tick Tock Diner - Clifton, New Jersey

I painted all the neon tubing freehand.  If you compare the 2 jpegs, there is no initial underdrawing done on the neon whatsoever.  I don't want to sound cocky, but that amazes me. How am I able to do that without screwing up?  

I hope that I will have this skill for many years to come.  

I think I'm going to darken the sky at the top and let it get gradually lighter towards the bottom, thus creating an overhanging arch of sky framing the sign.
