Beauty is in the eye of the beholder ... however since you asked, whenever I see this I think it has very good elements, but not together necessarily. It is a juxtaposition of sorts in my eye. Just my thoughts, funny you asked because the photo has conjured up thoughts in my mind since you first posted it. So, it is thought provoking.
I first see the extremely asymetrical Chawan, that screams out keep it asymetrical, wild, nonconformist, informal.
Then I see the Chashaku so almost perfectly, formally placed. Symetyrically dividing the photo/Chawan, formally placed, vertical in the photo. It would almost be better if it was just thrown into the Chawan. I first thought it was a side by side comparison of two Chawan-s cleverly divided.
Sort of like a tie on an orc.
On the other hand, it reminds me of the symbol for yin/yang.
But that is just my 2 cents worth.
