I used 23 colors from the Cheerful-32 palette by SoundsDotZip. I've been working on this off and on for a few months. I may work some more on it.
TrippY! I think the weak spot are the 1pixel stars in the background. They are too evenly spaced out and too uniform in size.
Thank you. I had a blotchy starfield and 2X2 stars. I got rid of those things right before I posted. I'll rethink those ideas. Since I've posted, I've noticed one of the nursery stars needs scooched a bit.
My blotchy stars were sparse. Since you asked me to rethink it, I realized I needed a lot more stars. I'll work on cleaning this up. Thanks again.
