Sexy Chicks Puzzled

This is a pretty difficult game where you have to find the differences between two pictures. Use a hint when you get to a dead end, even after that it will not be easy to find the differences. Sometimes the differences are so subtle that nothing seems to have changed. For each correct answer, you will receive 15 points, and for each mistake, 5 points will be deducted. Try to assemble the picture as quickly as possible to set a record for time and points.
