story game pictures

[ad51201]

What am I doing wrong??

I can not get the picture for getting 20 stars on any section of the story mode. The others I get just fine....but not the 20 stars one.

I made sure to play all the songs on the same level with the same instrument. And nothing.

Please help.

You probably need to play the "Chapter Challenges." Those get you two photos each.
