For this one, I experimented with widening the gaps between colours, and also building around things like the smile and eyelashes to make them, instead of building them in. I had a bit of help with the flowers from an artist friend (And also totally used that bottom one to cover up an area I was struggling with making look nice, shhh, it's a secret). I also had no idea if Yellowstar's eyes were yellow, or purple, so… uhh… yay, she got both!
Anyway! Here we have a stained-glass headshot of best pony, Yellowstar! This image is absolutely not a memetic hazard! You should read her book!
