From what I can see of your pieces, they is very little difference in the piecing. The pattern looks like it will be very forgiving as none of those slight variations have to match up against another pieced block. As for the floral mitered blocks, the ones in the link don't match the pattern either. The only ones that might concern me would be 2 on the far right where the little gold stripes don't match the others. I would just strategically place those maybe one in opposite corners so they were less noticeable. It is going to be beautiful so, STAY CALM and QUILT ON!
