My suggestion, since you aren't happy with where it is: Move the butterfly (in the square it's in) to the right, so that it is centered between the bottom and right hand seams of that square, and just off the flower bud. Very like the position it's in now, but moved counter clockwise to the right. I think what may be bothering you is the empty space below the flower bud in that square; if you fill it with the butterfly it will "balance" the block better, as ILovetoquilt says.
