Thanks, design is originally Pluww's, I forgot to link it to description but I just made my version of the character. I agree, it's really cool mix of animals. There actually is peacock dog in Persian mythology called Angha/Simurgh [link] though the one I painted doesn't have wings.
For painting, I used Talens designer's gouache. I've only made couple of pieces with it (this and Marceline), earlier I've used watercolors and non-brand gouache mixed together.
Awesome! I'll have to see if I can use Gouache when I'm drawing pictures.
Thanks for the link to the Wikipedia article on the Simurgh! Apparently, it was unambiguously female, sometimes had the head of a woman & was big enough to carry of elephants or even Whales! That sounds like one awesome dog to me.
