Jake has got his back and his right, he's probably the best swordsman in Ooo and he has no training or structured technique at all. This stance = Jake would be perfect for intimidating though, and I'll guess that's the point, and by his stance I'll wager his foe is several meters away, Finn should be able to react well enough.
I did know that, and I even dragged the image into google image search and everything! I typed in things from 'deviantart' to 'artist' and to the moon and back! I'm really glad that I was able to find you though, and it's absolutely no problem at all for the watch, I'm just glad I could follow your artwork!
