While I generally agree that the mid-outer limbs (particularly on the left side) can bend a little more, I don't think this tiller is far off. The mid-outer limbs are stiffer, but I think they are bending some, and it won't take much correction on the left limb to get a the outer limb working more. Be careful not to over correct!
Also it seems that your recurves are actually working a little bit, which is rare, and difficult to achieve/maintain.
All in all, good effort. 61# @ 26 on a 60 inch oak recurve is nothing to sneeze at, and your set seems reasonable for those specs!
