Doesn't blend, and looks awfully simple. Looks like you had a black background, slapped on a render, added some grunge brushes and a c4d. 4/10.
you should darken the left side and put a light source somewhere around the top right corner (not in the top right corner). and get some colours in there
it does blend lol and thats a good way to start (the black background and brushes and shiz). atleast tell him how to improve it >_>
It's okay for the render so 5/10
