#1.

Number one makes really good use of color and sublties and maintains a nice theme throughout the sig. #2's a bit too bipolar, honestly. It's super-bright on one side, and then dark on the other. On top of that, the pink chosen for the background doesn't really go with Osaka's coloring. :/ #3's good, but, well, there wasn't much done. Also, the cut/blur job on the subject could have used a bit more time.
