Thanks Angus for the kind comment... don`t really know but maybe I go for that tunnel idea in my last road sketch I will do. A road sign is definitely a good idea for all the concept sketches.
IŽll throw some more details into the final sketch I`ll choose from one of the 3 concepts.

a snow typ of scenery.
