Everyone should create whatever makes them happy to create :) I never tire of looking at renders of any subject matter and in any style, so welcome all shared works here.
For this one, as mentioned it would be the shaders - the skin looks too shiny and too plastic for me, and similarly for the clothing material. Now, clothing in the future may look that way of course, but I felt it was too shiny and solid looking, particularly for the hood which to serve its purpose would need to have flow and movement and be a fairly soft material, so I'd go for something much more "fabric like" there.
