It's looking pretty good. But you have like a mollegabet tiller going on. While your bow does not have stiff levers. It is a result of the limb being too wide near the ends. Your limbs are still 1 1/8" wide 7" from the tips, correct? In the area about 10" to 5" from the tips, the limb would have to be VERY thin in order to start bending. I would start tapering the tips earlier on. Taper the limb about 12" from the tips, to a uniform width taper, ending in ½" wide tips. You will essentially be doing side tillering by removing the excess width near the tip area. It will allow more bend in the outer limbs, which is beneficial for the elliptical tiller you're after.
