love your creature design here with your creative texturing! It reminds me a lot of some sort of mythical living drift wood creature made of bark less beach wood climbing with lichen and other mosses growing off of him. Anatomy wise, I think your pretty close with just a few areas I would fix, I'm not completely sure what type of deer you were basing this design on, but I believe the head and neck are a little small and could definitely be bigger compared to the rest of his body, along with that his stomach section is too inflated and round, dear are rather slim for there agile build and would have a lot more definition separating there hind quarters from there mid section in this angle. Lastly, I see you've got all of his legs tucked up under him pretty hidden, I know drawing hoofs and legs can be pretty challenging so I modified your design a little and included the legs, more clearly defined and form wrapped to help you reference. I hope my paint over helps and shares some light on answering your anatomical question. As always keep up the good work, and keep on practicing my friend! Don't skip leg day.
