OK I have to applogize. If the second photo is an actual usable bow I am wrong and sorry for my bad judgement.
But to me the bow looks like a pure decorational thing. The limbs seem far to thick and stiff to bend and from my judging will rather break than shoot an arrow.And the string attachment doesn't look save under any applied pulling force.
Don't get me wrong. I don't want to critizise your work, but only express my doubt regarding the functionality of that bow.
By the way: Did you realize the picture is called connor_s_bow___aciii_cosplay_by_drifteruk-d613q9k.jpg
I think that gives a strong hint that it is a pure decorational thing and no real usable bow.
(connor is that guy from Assassins creed III) So yes I am wrong. it is not out of a fantasy comic but out of a game.
