Nobody pointed out that the head is obviously the wrong dimensions? Make it a square image. 128x128, to be true to TB. In addition to what Mrama said, it's very obviously a copy/pasted image. The "face" on it has nothing in common with the background, at all. If you're going to do a theme like this, make the face components actually mesh with the image (e.g. stars for the eyes, or whatever.)
