I don't really want too many people to see this at this point because it's still just a sketch with a pretty good deal of errors and such (I'll point them out below to alleviate confusion), but I at least wanted to show what I had so far for this viking horse I came up with earlier today.
Her name is Brynhildur, an Icelandic name meaning "armored warrior woman". She's based off of an Icelandic Grey Dun horse. She uses a warhammer.

Errors:
She's wearing sleeves, those are not her bare arms showing, I forgot to put wrinkles there, so please don't be confused.
Her right hand is too flat and angled wrong.
The chest strap doesn't interact properly with her bust.

I was told about these while my boyfriend looked it over, and I'm currently working to fix them so that I can scan it in properly and ink/color it in SAI. So hopefully soon we'll have a viking running around on my page. :3
