I had a lot of fun with this ACEO. I heated the copper after embossing it to give the surface different tones. I then added a layer of black acrylics over the ACEO and rubbed it off to highlight the peaks and valleys. It is full of texture and it is a lot of fun to touch.
Clicking on the image will take you to the listing on Etsy and you can see additional pictures including one of a side view so you can tell how much texture there is. I hope you like it.
