he is pulling bow wrong, not for european archers but in horse archery, archer pulls the bow with his thumb and using a thumb ring(which called "zihgir" in Turkish.) and puts the arrow to the right side of bow( if archer is left handed he puts the arrrow left side of bow.) and another mistake horse archers do not carry quiver on his back , quiver must be on his waist. for more info you can ask me.
The same thing happened to me with a bunch of wolf pups. At least deer can't attack you, but the wolves would have killed me if I didn't kill them first, but then I felt bad for the little pups whose mom I just killed.
I love these screenies you make! As an animation student it kinda makes me want to do an Assassin's Creed Animated sereis once I ahve a good foothold in the industry. I'm strongly reminded of Hayao Miyazaki's films, I don't know if you do requests but you should do another one of Connor on horse back shooting an arrow and base it on a screen shot from Princess Mononoke.
