Tarzan Taric (skin)
This is a simple idea (it has probably already been suggested!) but could very easily be done in a relatively short amount of time.
Taric's facial features and the Disney character Tarzan are similar in terms of structure: http://vignette1.wikia.nocookie.net/disneyfanon/images/e/e2/Tarzan_Character.png/revision/latest?cb=20160304173653 http://am-a.akamaihd.net/image?f=http://news.cdn.leagueoflegends.com/public/images/articles/2016/april/tins/9.jpg
How to do this skin?
Definitely needs a loin cloth...but the skin needs more than that. We need shoulder pads, so I would suggest some carved rocks strewn together with some jungle vines. Bracers made of a jaguar's hide could be the material of choice, though going with brown leather would be fine. A bone-tooth necklace could work for provide some chest decor. Tribal face paint could provide interest in the face. For the legs, it would be nice to have some sort of "leg necklace" for lack of a better work containing bone in the upper thigh, but overall most of the emphasis I believe should be placed on the triangular loin cloth. His weapon of choice could be a wooden club or even a large stone with a bone handle or a skull hammer. Any of these combinations could work for a real jungle-man feel.
For abilities, it would depend on the scope of the price. If this skin were to be made and it's worth was 975, then no chance would be necessary. For a 1350 ability, obviously a brownish greenish ability overlay with the dropping of gems in favor of stones and vines would be prefarable. If an 1820 skin was wanted, then it would be absolutely a thrill to have Taric yell like the classic Tarzan from the Disney film when the ultimate went off, and have a series of questionable grunts. I believe that the voice actor for Taric and the Disney Tarzan are very similar.
tl;dr Just a fun skin based off of the Legend of Tarzan, which FYI is a classic story that was simply made into a film by Disney
