get it? dinky? cause she's a mini?
anyway, I like to draw reference sheets like this to help me solidify a character for myself.
This is only a sketch, so a nicer version may be uploaded in the near future.
But have a small description in the mean time:
"This is Inky (Dinky) Donkey
She currently does not have much of a back story, But she admires ponies so much that she wants to be like them, and thus wears a fake cutiemark sticker upon her flank. She loves paints and inks but she's VERY clumsy, and lacking in much grace- and let's just say that some of those spots (not in the picture yet) weren't always there by natural means."
