Bad render placement, read a tutorial regarding rule of thirds before you start working on actual tags.
As for the tag itself, a lot of effects who were randomly included in the signature.
None of the make the render blend or whatsoever.
The flow is very messed up, you need to work on it.
The font should never be put in corners, ever (the rule of thirds also applies for the text).
The colors are pretty much giving me a strange feeling.
An example of a neat tag made with Akali render;

The colors are fitting perfectly, the background is not messed up at all, it creates a nice flow.
The background is blurred and the foreground is sharpened with a lower opacity which makes the render blend even more and gives a warm feeling.
Light sources are not messed up, usually corners are darkened and there's one spot most of the times put as a light source (above her head white 70-80px dot with lower opacity) and the text could be better but still blends with the tag itself.
