Thank you for your feedback (and the praise... because I firstly did not like my painting very much). But as I wrote in another comment, the atrocities of the Nazi Regime are for me too much to ignore them. In my view there are enough different symbols to use, it is unnecessary to try to redeem such a symbol as the black sun. Maybe creating new symbols with more positive and life affirming connections could be an answer.
But you are right, I was a little pessimistic in my post. This seems to happen often for me while doing art – sorry for this.
