the lighting in this is false.... thats the main thing i seen, your light source should have been on the right as the shadows are on the left so kind of buckles the render under it.... very clean though "ins" kinda gets lost to the c4d. simple design but works in me opinion, the border seens really overpowering in this... normally everyone has a black border, but with your softish look, its way to much, try halfing the pxls on it. compostion is a little right heavy to me though with the, window, clip mask whatever that is one the right overbalancing the sig, a lighter exposure maybe would hav even'd it up...
room for improvement but mainly change that light source :p
honest 4/10 its nice but visually i can see exactly what u've done, next time impress me more
(am now sayin exactly what i feel on ratings... 1 being a beginner sig, don't take 4 the wrong way)
