I did an abstract then put a backdrop of clouds to give it texture then I put an equalizer on it , adjusted hue and saturation- then added a spotlight effect- I was going for mountains w/ a solar eclipse
It does look like Murano glass! I love the spotlight on the top left side but do wish I could see the entire "dip" of the bottom part in the center. Maybe if you curved that bottom black area a bit more so it's high on the sides and lower in the middle? Just my thinking - it's your vision!
