First let me say welcome to the addiction.
Second, you will find that you get the best feedback on the tiller if you post: 1) unbraced 2) braced and 3) full draw photos. This way we can see how the bow bends and we know what kind of lumps and bumps the stave had before bending.
Assuming your stave was very straight, then yes, the tiller on the bottom limb is not the greatest. The limb is hinged right out of the fades.
You could potentially keep tillering until it's not hinging anymore, and then shorten the bow by a couple inches to get the weight up a bit. If not that's ok but the bow will probably take a fair amount of set right at that spot.
Eventually ever wood bow will fail, and always at the weakest spot. That bow WILL eventually fail at that hinge. It may be 1 more shot or 10,000, but when it breaks it will be that spot.
With that said, the top limb is looking very good, especially for a first bow. Maybe slightly stiff in the outer 1/2 of the top limb, but nothing to worry about.
I know you can tiller because the top limb is good, and I know you can judge tiller cause you noticed the hinge, so now it's a matter of taking the time to make sure the tiller is AS PERFECT AS POSSIBLE on all your future bows. Go slow, post pictures during tillering if your not sure, and help will be offered by many here.
Again, cheers and welcome to the bench.
