Thank you all for the encouraging words. 
The opening was yesterday and my work was definitely noticed! The visitors found it different ("never seen anything like it"), colourful, but most of all: beautiful and even intriguing. I noticed that several people came back to look at the work again. One woman, who was first accompanied by her husband, came back later with a girlfriend: "Look this one is so beautiful!".  Felt very accomplished ^_^
