These two are Rose's adorable Pandaren couple Anying and Irohne, doing some romantic evening flower gardening. I had to draw Irohne holding something tiny and delicate, since he has such big paws.
I tried to do a combination of the WOW in game scenery and IRL plants -- Irohne is holding one of these: http://davesgarden.com/guides/pf/go/876/
and the foreground lilies are these: http://davesgarden.com/guides/pf/go/53513/
the little ferns and lichen on the edge of the mountain/hilltop where they're standing are just general ferns and lichen, though :)
