You can see all the potential leak paths at the back of the engine from that pic. All those already mentioned plus the oil cooler and seals, oil filler tube, thermostat pulley bolt even the breather tower. Dip stick boot is probably the most likely and fairly easy to replace.
Plus the oil gallery plugs at the rear of the engine near the fan have been known to leak or in the extreme pop out.
