I don't give CnC much, but since I'm a fan of that little Cudster, I'll do it here.
So, first off, I see you figured out how to do the clipping mask on the text, so that's good, but the font isn't too great, and the distance between "Enter" and "Galatic" feels off. Move the two words more together, and then closer to Cudi. As for the smudging, I don't really see much of it, but from what I do see, it's a bit blurry, or at least near his shoulders it is. Blurry smudging, especially near or on the stock never looks right. Also, the colors are pretty bland. Go to dA and download some preset curves to use to improve your colors. Those almost always add more flavor to tags.
Overall, tag's pretty boring, but it seems you're starting to improve a little. But yeah, download some curves, or experiment in making your own; maybe even download some bubble C4Ds.
