Gonnie you clearly have your own style of working with wax. And this painting fits so well with that. You let the wax guide you.
A bridge is a very meaningful symbol, think of; progress, connections and stability. Often people view bridges as a way to reach a destination, and therefore bridges are a way to overcome obstacles. Bridges also represent transitions. "Crossing over". From the world below, to the world above.
You perfectly bring these worlds together in your painting. Well done!
