Its ok .... the render isnt good too dark for what your doing you need a lighter render because not onlt would it stand out better on the gray scale back ground the blur on it would add a bit more depth you see the way the whitish symbol sits on the gray thats what you want also the symbol shouldnt be blured but prehapse opaced a bit expermiment
Texts should be there long and be a better color in the middle such as dark ish blue
Thats a long list of problems but most are down to render and color so im giving it a good hearty 7
