I'm not happy with this block, but it's only the applique, not the piecing.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
This is where I'd change things. I chose reverse applique. My melons look like eggs.
Then I studied the photo of Jane's block and I'm pretty sure she did not reverse applique the melons.
I'm going to redo this block and applique the melons on top of the block.
