Congrats on taking that first step, even if it's cracking up on you , you've had those first shots, which you just can't beat.
You'll soon learn to get your eye in with tillering bows.
I do a blog 'Bowyers Diary' where I show what I do, even the mistakes, have a look as it may be useful, there are some tillering videos too on my website 'Delsbows'. Just google those names to find them.
That first bow teaches us so much, and we never stop learning.
Good to have you on board!

(BTW On my blog I've just finished my fisrt successful Hornbeam bow, the first one I tried smashed, that's all on there too!)
