Oh man, that bow is so LAME! Boring tiller. If it doesn't have at least twenty knots, it doesn't count as a bow, Druid!
Just kidding man. Love your tiller! I always do. Myself, I'd give the bow some personality by adding a simple leather handle and maybe some tip overlays. But such a plain stickbow as is, can also be really intimidating when someone tries to draw it.
