Good Job ! I just finished a 10 minute block as a baby gift and working on one for a wedding gift. I did have my friend put embroidery in the center square but it was a plain block with a hawaiian hibiscus flower all one color. Your fabric is all different in the center square so I don't know how that would look. But all your fabrics do co-ordinate ! I like all the color you have going on there ! Beautiful !
Happy quilting ~
