'The March' by Lauren K. Cannon
I am not an expert, but I have to say that this is epic and imposing. I can even imagine it being a cover art for a book in the genre and the landscape is brilliant. I also enjoy how the soldiers are not portrayed as individuals, but as hazy figures that merge into a great serpentine beast that is an army on the march. Usually, I am not moved by such pieces, but this one I would definitely love to hang on my walls at home.
