I love the pinks. They show movement, and their wings are beautiful. It doesn't matter that they're commons, they're still one of my favorite dragons.
The splits are wonderful also. I think how the colors are opposite on the male and female sprites is just a great way to tie the two genders together without two entirely different sprites.
The noctures are amazing as well. The day version has such powerful looking wings, and the night version has beautiful shading. And I love the position of the gendered night hatchling sprite.
And of course, the frills. I had forgotten how much I loved them, as they were one of my first dragons and commons. But the colors make them so amazing.
Thank you to all the spriters!
