This is one of the most difficult things I have ever drawn! But I am pretty happy with how it turned out!
I've been roleplaying with Digifun for a few years now, and we have an ongoing story featuring my Fursona (Uisce - the horse) and one of their characters (Suzuko - the fox). We're hoping to someday turn that roleplay into a more finished story and release it as a Visual Novel. For now however, this is sort of like a piece of promotional art for the story. It isn't actually based on a particular scene in the story, but it is more symbolic of the character's relationship with one another.
This is probably the most "basic" form I have shown Uisce in as I usually at least have her sporting some lightning on her back, however, as a shapeshifter she isn't always showing off the full extent of herself - despite what my gallery of her demonstrates...
