A concept artist who has particularly captured my attention is Keith Thompson. What initially drawn me to his work was their distinct dark and/or gruesome quality. He appears to have a great talent for depicting disturbing and yet somehow believable characters.
I find his attention to detail quite incredible, whether it be the folds in clothing or the gory wounds in a character's chest.
I find some of his art reminiscient of the films of Guillermo del Toro, whose work I will also be exploring.
