Like brjogg said, 90° off of this - this would be the right split direction.
Now you have a bit more work to do, but that's it.
Chase the thick nice ring, about the forth from outside. Bring that stave to near dimensions, have in mind what design you're looking for. If it would up to me, this would be a good candidate for HLD. If you're a beginner, go with absolute flat belly.
You can show your work here and there are a lot of guys helping you.
The stave is long and you could also make an ELB, but that is not what I would like as a hunting bow.
Be sure the stave is seasoned enough before you bend that stick!
GOOD LUCK!
