Kyou well let me tell you its bad...
simply... the render looks kinda horrible
the background is nice but has nothing to do with the render
and text well quite the same thing...
too many black spots
render is just pasted in
there is no blending nor no effort to make both the background and render
have a similar meaning...
try to make this copy paste the render everywhere in the background smudge it
add some effects to it like glass effect and so... paste the render and try blending both
give some depth to it etc...
