None of the pictures are all that useful there need be only two pictures and the one that you got in the area is of no use you need to be looking straight at the the wing tips the camera level is two low in the the only picture from the side You need one from the left side of the airplane and you need one from the rigtht side from the same camera position. Also you need to prop up the tailwheel to a roughly level fuselage position.

What ever slight horizontal stabilizer tilt may be present there is not going to be causing a severe roll. That may induce some odd coupling in some advanced aerobatics but not the severe roll you describe.
