It's okay
(a) It's primarily a photograph that you added a 3D model to. Since the Art Portal bans photography, the only "portal-appropriate" part is the 3D model, which is small, overly simple, untextured, and not very captivating.
(b) The primary light source is correct, but there's front-light on the apples that's not on the model, and his specular shading doesn't agree either.
(c) That creature's structure is confusing: is that a nose, hair, an antenna, what?
(d) If the apples and droplets were in 3D, you'd have gotten more 5/10's.
