Photorealistic Concept Art for Short Horror Film

I am seeking an experienced concept artist to create four (4) pieces of concept art that will showcase key moments from a short horror film that I am producing. The art will be used as part of a pitch deck and/or business plan that will be used to try and secure sponsorships and additional funding for the film. The film is about a young woman who suffers from chronic headaches which manifest in the form of a horrible creature that psychologically and physically terrorizes her. See the attached for the creature design. Additional reference material and scene descriptions will be provided to the freelancer whose bid is accepted. Final images sizes must be at least 3450 pixel width x 2700 pixel height. Please provide a link to samples of your prior work and contact me with any questions.
