It's bending more now, back to about 20" at 50# on the taut string, but I'm thinking it's rather a short bow for 28" draw.
So, how do you lengthen a bow?
You can actually splice a few inches of extra tip on, a bit like the Siyahs (levers) on an Asiatic Horsebow, an extra inch or two doesn't have much leverage on the join so you can get away with it.
I don't want to do it on this bow, as I want it nice and clean and simple. The other way is to extend the other end of the limb by reducing the length of the grip.
I cut back the grip by about and inch on the upper limb and blended the grip into the limb, back onto the tiller and the draw length at 50# had increased by an inch. The grip has been narrowed a bit to give me an idea how much I have to play with.
You can see it's looking more like a bow now, but the outer limbs are still not working hard enough. and the right limb is a bit stiff.
