It did indeed came out very nicely! I am also building kamelen ngonis, but with gourds. Always wondered if I could replace those with something else. What kind of polyester do you use, specifically? An epoxy? What is the fabric you use? Glass mat? My hart is bleeding a bit, though, to see you working outside with all the plastic dust. Nature is already filled with too much plastics. I'd also suggest to put more tension on the skin.
