Tiller is very nice, but just to be picky, the right limb looks just a tiny bit weaker in the first third of the limb. Depending on how close you are, just stay away from that area and do a couple extra scrapes each time on the left side.
As far as the twist, make sure as you are tillering that you are keeping both edges of the limb the same thickness. If the string is still tracking through the handle, don't let it bother you too much.
If you're at your desired poundage at your desired draw length; just sand it, finish it, and shoot it!
(oh, and it looks like you have a LOT of wood past the string grooves. You only really need 3/4". That'll add a few fps and lessen the hand-shock)
