When I put the other three sides on it it should all be correct, I think. Of course I am talking to the two drafting queens so I don't know.
Piece #11 should be a triangle and should not be added until all of the diamonds have been sewn after folding on the lines. It looks like you might have added it before folding. If you cover up the seam allowance on all 4 sides you should see 1/4 of the finished block.
