Top right seems to be the best.

The others:

• Top left: Mystery tongue coming from or going somewhere
• Middle left: Much to bright, hard edges make finding icons difficult
• Middle right: Too many dark areas
• Bottom left: Might be okay as well
• Bottom right: Too bright and might not fit the mood as this seems to be an anime inspired background
