Sure. I've got a lot of angel ideas floating around in my head so making one would be easy. Since you've mentioned a non-SPN angel I actually do have some angel characters that I've been itching to draw.
you do good work I know the demons and levi's are going to be awesome hope you do dragons and phoenixes hell even if you don't what ideas would you give others to draw them instead should they look like the myth says or should they have a humanoid appearance like other creatures of supernatural
look up the show angel then type Illyria because its to much to explain and i don't know how to make a link to the site but ill will say this It( i call illyria an it because she doesn't really have a gender)is a creature based after H.P Lovecraft's The Great Old Ones It would call demons like meg and Crowley half breeds and vermin and call Lucifer and Michael pests
Thank you .Ah, don't be envious! Yes actually, I combined the goat and human head. I wanted to go for a more subtle approach with combining the different heads on Cas's angel form, especially with his main head.
