I wouldn't cast toward that big red arrow I'd get hung up on it. Seriously, I'd cast up stream with some sort of nymph and try to get it as deep as possible. And to be perfectly honest, I'd cast to the right of the angler toward those (not sure if they're roots or tree limbs sticking up from a sunken tree???) So no doubt I'd have scared that big brown off and never knew he was there.
