I think these look great! I imagine the choice of fabric and arrangement of the blocks would play a role in how obvious 'high heel' design is.So, the quilter would have a choice as to whether they wanted 'high hells' theme, or just a cool abstract design. I studied art and design at college and a lot of what we were encouraged to do was to 'break down' - eg. making a simplified version, focussing on one element - an object to inspire our work. The above block has done this really well.
