I agree with Paul that it appears to become pretty whip ended. Stay away from that last 12" of limb length on both limbs! I know you've changed the tiller already since you've taken that pic, but for what is worth it...
Tillering character bows is tricky. We need at least an unbraced, front profile and drawn picture to make any comments on the tiller. But preferably, we need to see it being drawn, as you would on a tiller tree, by making a movie for instance. Just a static picture of a character bow at full draw is useless for judging the tiller.
