I do not know if you are a sci-fi fan, I am and in 1984 it was one of the greatest sci-fi movie of that time "Dune". Set in the distant future, the film chronicles the conflict between rival noble families as they battle for control of the extremely harsh desert planet also known as "Dune". There were huge sand-worms there, they could move underground but when they come up to surface to get their preys. Your artwork reminded me those sand-worms but in modern version. and the surrounding looks like a desert planet.
Beautiful art work @xpilar
