Hmm cuts and patterns like those are quite rare in WoW. Your best bet is to browse wowhead for low level leather gear. Upon a quick search i threw together this: LotR-Ranger Gear
If you have a character that hasn't done the cataclysm quest lines this set is rather easy to achieve I'd say. (Maybe apart from the hood.)
I assumed you are alliance so one or two pieces are alliance quest rewards. If you are horde there are equivalents, just look under the "see also" Tab on wowhead.
Maybe there is a darker/greener equivalent of the chest and legs in a different level range but i didn't find them. Maybe browse wowhead for pieces with the same icon.
