Yew is truly beautiful wood. You've made a nice bow... but. When I first saw your full draw pic, I said "Oh, boy!"
Can you see that your bow is doing most of its bending in the first 6-8" of the limb, and then the limb is mostly straight? Mostly in the top limb, too? If you got more of the entire limb working, your bow would be much happier. I mean absolutely no offense... I just hope you can see what I'm mentioning. If you were to get the middle and outer parts of the limb moving, that would be better. The bottom limb is not as bad, but the top limb could really use some work!
You've done a great job on the tip overlays... nice work.
