Tully a beautiful piece, the lighting and depth in every object makes a majestic and realistic impact. You can really see every attention to detail as you look at the castle to the landscape. I even detect the faint hints of smoke from fires within.
What really adds to the drama to the piece, is the angle from which we view the castle with it's towers and turrets looming above. It gives the place power and importance.
Overall this piece is so crystal clear in it's vibrancy and realism that it's worthy of concept art in any production studio. Talented artists can take us into their imagination, and I would say that your work has accomplished that.
