Entry for Raven Feather's contest. :'D Because you said you liked natural colours I started with some black and white, and the speckles led me to go with a kind of space theme. I also threw in some cobalt blue with the speckling (which is pretty much random, by the way, but there are more speckles closer to the big markings.)
His accessories are a bandana with a sort of nebula design, a telescope necklace, and two silver ear piercings, which are unfortunately a little hard to see on here. I hope the blue specks don't make it too unnantural.
Hope it looks okay, Raven! Let me know if you want anything to change or to post the version without accessories!
