The text looks almost identical, except now it has more of a white shade. The biggest problem with this tag is the head, which is generally what you want to use as your focal, is above where the focal should be. It would look better down and to the left a bit, near where those two somewhat sharp points of the chest meet.
Look at your Aang sig. You see the arrow on his head? Around the tip of that arrow is the focal point. If you placed your render similar to how you have Aang in your current sig, it would look better. This is very fundamental stuff... so I suggest you learn it now and get in the habit of doing it right.
Also, I think you downsized the render too much. Generally you want it to be pretty big, but not huge. Another thing is of course what Mariah mentioned, being that it is blurry. I don't know if you followed my tut or not, but if you did you are supposed to erase over your focal once you blur the entire tag.
