the shooting is what probably changed the tiller, thats why a lot of folks tiller with a positive tiller- with the bottom limb stiffer than the top limb.
i have since learnt to shoot my bow in with few pounds heavier- so that i can do my final adjustments after shooting in, and i just draw a few inches shorter - so that i never draw past my intended finished weight.
you wann see my first few bows- yours looks mighty darn fine- at least now you know now for the next one!
very nice workmanship
