I am curious where you attack at with this style of play. it seems like it main strength is that it defends most attacks coming from the opponent's rook side, but I don't see how you advance your attack.

first of all 44 pawn is left hanging.

Hi,
first, you'd have to go beyond this study, as these variations are not exactly mainstream. Two, Ishida is broad and tricky. There's Haya-Ishida, Masuda-shiki, B-77 style. Sometime you even sacrifice the Nx85.

These videos are a bit old, but it should give you a good basic idea of the strategy:
