The action is still higher in the second picture than I’d use myself. You could sand the shim a little, but I’d have it so that I could always set the action lower if I wanted to, rather than be unable to lower the bridge any further as it’s already on the body. Full string tension will pull the rear of the bridge forwards, even with locking studs, which angles the bridge and raises the string height slightly. IMO it’s better to have the bridge 2mm off the body and then be able to adjust to any desired action.
