It probably wouldn't hurt to string it now at a low brace height. But I can see some room for improvement at this point, so there is no need to pull it any further or to string it. As soon as you see any stiff spots or (almost) hinges, you stop pulling it any further. You'll need training to see those minor problems early on in the process. Try to see that hinge in the right fade that was pointed out to you earlier on. (Not a true hinge, but more a slight weak spot.)
You've done good, because that 'hinge' is not nearly as pronounced any more. However, the right midlimb is still a bit flattish. It could need some more scraping, but you're really close. Ten agressive strokes with a sharp scraper is probably all it needs. At the same time, left limb is slightly stiff between midlimb and the handle fade. Scrape the area from midlimb up to 6" from the handle fade. Don't touch the handle fade itself.
Could you perhaps please post a picture of the front profile of the bow, the width lay-out? The front profile dictates where the bow should bend most, and whether you should be aiming for an elliptical or more round tiller.
Also, I presume the bow is straight when unstrung? Or did you glue in any reflex?
