What are the weaknesses of pygmalion?

As in the mythical figure Pygmalion? If so his weakness was that in his quest for perfection (aka the woman he sculpted, who was so perfect and beautiful he fell in love with her) he overlooked inner beauty, and instead only looked at outer beauty. When he pleaded to the gods to bring his sculpture to life (and they granted it to him) the woman turned out to not be perfect - which created dissatisfaction. Therefore Pygmalions shallow view of perfection in itself was flawed - deeming beauty as what constitutes perfection.
