Honestly, you made several tillering mistakes, but in spite of that it's not bad at all for a such a challenging piece of wood. It looks darn good overall, and the mistakes aren't fatal. Nice and rough looking, but gorgeous, and "net" tiller, well, I've seen worse.
But, without criticism, let me throw in a few thoughts for the future. If you look at your unstrung pic you can see how all the set the bow takes in concentrated in the middle of the bow. On a longbow that is the thickest portion,and should bend, but a tad to a good bit less than the outer limbs. Likewise, if you look at the drawn, prefinished pic, most of your bend is in the middle of the bow. This is "wrong" for such a long, deep section bow, and results in high set, and heavy tips.
Divide the whole bow into thirds mentally. That middle third is bending the most, above and below the handle. Now, mentally divide each LIMB into thirds. Looking from the handle outward, the top limb is bending a lot in the first third, too much in the middle third, and hardly at all in the outer third. The bottom limb is bending too much in the first third, not at all in the middle, and almost not at all in the outer third. It should be some on either side of the handle, more in the middle third, and about like the middle in the outer, except for the very tips.
I see that the splint/wrapped area presented a technical problem, but right past the wrap is an are that could have been made to bend a lot more, which would actually help the tiller AND relieve stress from the spot you wrapped.
Keep it up, brother, that is a good start.
