Bee block for Bella

This month in the 'Bee seam piecing downunder' group it is my month. I have chosen a basic block using my moda basic grey - blush offcut range. I love the combination if pink and aqua with just a hint of chocolate. However i think it does need something in the middle.......

I am thinking maybe applique another square in the middle ???? Not sure... may just have to wait and see all the blocks returned before I make a decision.
