I found a site that lets you turn any custom species into a breedable adoptable with different layers and genes, and I thought a few people on DA might be interested. (All free, you don't need any token or anything to create a species) . Pity this group is dead, man it's been a long time since I've visited deviantart. Anyway, still letting you know it's somewhere you can use your art for fun.
