Hmmm yeah, its shakira.
kind of easy, pedro.
Why not you try to find a good pic of artist that you want us to guess, you make it as puzzle with undone part, first you can start with only one puzzle piece, then if no one could guess it right, you could reveal another part/piece, its like you can divide the pic into 9 pieces / parts. Its more interesting, I guess... Yeah, just suggestion.
