Takkun GMV. Even though it's not his best, Takkun's shows much more experience and knowledge of the basic workings of design. It's simple, and not too cluttered.
Sempai- It was a bad idea to use that render in the first place, it's pretty LQ, which automatically takes down the quality of the overall work. Second, there's no blending, other than a likeness in the coloration. The piece is quite oversaturated and, while the text is creative, it just doesn't fit. I'd recommend reading some tutorials, and picking up some pointers on these problems. :]
Takkun- 5
Semapi- 3
Takkun wins this battle, good job everyone!
