Hi,
I agree, it's a bit whip tillered for a warbow. If you want to bring it further, get it bending more thru the handle. Bring the whole length around "full circle." If you try and bring it back more, you might break it, or cause a hinge. It'll be nice to shoot like it is, but it won't be a true "warbow."
Get "into" the draw a bit. Bend your knees, and round your back some, bending slightly forward at the waist. You're gonna rupture something shooting that heavy a bow with a straight up target style draw! Nice bow, otherwise!
