Okay here's the big ol' critique from papa flamermesitts
I see you have an understanding for coloring, obviously modeling had a hand in deciding where and what color and light to have. The hair in the latest one posted looks unfinished as it lacks the lighting the skin has. The censored one also looks unfinished as the environment around the dragon doesn't look finished either, and it kinda reminds me of how vincenttheguy did his stuff. I dig that sergal thingy, as the lines look well done and there is definitely a sense of depth. The lower part of its body is a tad softer and not as definite as its upper body however. I also dig the guy mounted on the dragon, it reminds me of a cartoon's concept art, which is great in that regard.
I like your stuff, but I'm not versed in that kind of subject since I'm not into it. I feel like you mainly have to build up upon the consistency of your works. Hope it helped out!
