Primitive Archer

 I think the main problem you were having was the low moisture content, like Cord mentioned. Yew really doesn't like low moisture content, becomes very susceptible to tension breaks.  I won't try stressing the limbs for at least a week after exposing the limbs to heat bending or corrections. Unless you live in a very arid climate I doubt you will have any troubles with unbacked yew, if its a good stave, and you follow the grain, compensate for any knots.

In future, non sinewed bows if they are going to be used for hunting, I would recommend that you back them with rawhide. It gives you a little more protection in tension, but more importantly it will help stop the sapwood from getting dinged, in the wild.

Here's a shot before I retinkered with it. You'll see it's already slightly whip tillered here. At this stage it had already been shot in over 2000x and had only 1" of follow, which I would call great.

Nice bow did you Mean to whip the ends. That’s what I see in the full. Draw pic.

I use Imgur, a photo storage site. It's free and it gives you options for sizing photos for different applications. I've used it for quite a few years now and have never had a problem with it.
 Before Imgur I used Photobucket which also claimed to be a free photo hosting sight. After a few years they decided to charge without letting me remove my photos. I lost over 100 pages of photos to Photobucket, many of which were bow building related pics, some were build alongs.
