I don't see much wonky and maybe with a little starch and pressing you can get it under control. A suggestion is to make flying geese units for the star points on all four sides. That would eliminate the four center seams. Any seam that is purged from a quilt is that much less bulk. I think you did a great job. I don't know the size of the block but you could make a placemat or something else from this block. We have ALL learn from our mistakes.
