My first attempt at using a png upload - background looks odd - not sure why it looks transparent - if anyone knows why - let me know. I'm re-rendering images that I've removed from dA (since dA has degraded) account.
I am not able to help with anything which may cause transparency in your art. But, I do like your picture. It's like in a lucky moment, your James Webb telescope found a red universe with a centering sun and orbiting planets.
Hey Jenny. I really like this but what are you referring to about the transparency? Being transparent should be a great quality and shows the layering effect that comes with many, abstract renders which always adds to the overall beauty. I like it for one:)BTW, what is dA?
