I noticed your quilled seedling has a watermark although it doesn't dominate the face. But you could bring that out more. I vote for the appliqued red!! It's distinctive with both a watermark and an applique! Or the first seedling which has both the hooked sepals AND a watermark and good color saturation.
I personally don't understand why people plant 20,000 seeds. Makes me tired just thinking about digging up so many rejects!! Having a purpose with every cross cuts down on the rejects!! And having fewer seeds allows you to properly evaluate what is blooming each day. I love looking at seedlings during the winter and mentally planning crosses. You'll notice features in photos that you missed in person.
