I have made nice little flatbows, with a stiff handles drawing 40-45lbs at 26", from similar staves. Limbs were about 1and 3/8"-1.5" wide.
You could eek out a longer draw with a bow that bends through the handle.
Your stave is quite deflexed. I would build a form to allow you to straighten the stave, with heat, or put in an 1" or 2 in reflex.
The first step would be rough out the bow, until its floor tillered. This will make any heat corrections easier to do.
I would also let your stave re hydrate after heat bending, for at least a week(no bending). Yew gets brittle in tension if dried out too much.
That being said yew is magical stuff, compared to other woods. So light in the hand, yet so springy, with cast.
There are plenty of things you could do with your stave, like recurve, and or sinew back it, but it depends on your goal and current skill level, and how much time you are prepared to invest in it.
As this is your second bow, take it slow, don't rush and you should come out the other side with a lovely bow.
