Aww... it's pretty. What are you using it for out of curiousity? It's quite nice. I was sooooo excited to see someone link their work they did. No one ever does but I wish they would. I love to see what people do with the brushes.
It's okay... there's no rush to use them or update. (most of the new features are not nessicary especially on the latest ones.) If you ever do use them feel free to let me know if you remember where you got them. If you don't no biggie.
