Building a Block

I need to design a block for the Block Builders Workshop page of the Jan/Feb 2014 issue of McCall's Quilting. It needs to include half-square triangle units, square-in-a-square units, and pinwheels, since the lesson will be piecing tips using half-square triangles. I started playing in EQ and came up with this possible block:

But I wanted to be sure it was a good block for placing in a straight setting. What do you think of this?

Nice stars pop out, and I'm liking the strong diagonals. It's a work in progress, but it needs to be done ASAP!
