Your tiller looks pretty good as far as I can see. I'd like to see it braced/unbraced, and closer up. I've only made one, from oceanspray, and blackhawk helped me through the tillering. I found it the most complicated and delicate tillering I've ever done. If I remember, he recommended ever so slight movement in the levers.
I had done what you did, using a picture out of one of the TBB volumes and yet I got a lot of criticism that the upper limbs were too stiff. By the time I got done getting the ever-so-slight movement clear out to the tips I had lost the poundage I wanted and shelved the project. But it shoots good for what it is. I did a takedown handle and rawide back.
But I think he is right and that the whole limb needs to work to some degree. Otherwise you have half a limb not working and therefore violating the rule of mass, etc. I kind of say that tounge-in-cheek because I think the design idea of a wide, working lower limb and narrow levers are the fastest bows. (I'm thinking hunting type bow). I've always wanted to explore this concept more but of course I have a laundry list of ideas that I want to get to.
