that looks horrible,the actual shape itself is ok but the render sucks and the mats you used are horrible and it looks way to low poly and block,some smoothing would help and the background is meh,the lowered opacity part of the render thats there doesnt help any and its dull as well.
A bit blocky here and there on the shapes. Very detailed and busy. Not to much variation in materials used. Maybe more lights? I mean light points in the image, not lighting up the model. But overall I like it.
