I really like these. Proposed addition: Kali Gandaki Gorge in Nepal. Since it served as a trade route from India to Tibet, perhaps one free merchant. (I assume you did not have the Grand Canyon to avoid too much US content.) Proposed change: Pamulke (spelling off), free doctor either in addition to or instead of healing units. Proposed change: Aurora, reduce its strength. Either a free technology or +1 happiness in all cities are each strong. Perhaps you can split these up between northern and southern lights, two separate wonders. Perhaps one could revise to +2 happiness in only one city.
