Very respectfully, here's my 2 cents ... go with the idea, but clean it up a bit. I say lose the cape, fix the sword and belt as Woodsheal advised, add a slouch cap. It looks a little "cartoon viking, over the top" to me in its present state. Have fun, and post pics. After the fact, you'll get nothing but complements, so if you want honest opinions, get them before the tat is permanent.
