エルフ is "elf", which is used on pixiv much the same way we'd use "pointy ears", not the way we'd use "elf". Not exactly the same, but pretty close. エルフ耳 is "elf ears", but it's honestly kinda pointless given the way pixiv's search function works. Searching for エルフ will find everything tagged エルフ AND everything tagged エルフ耳, while searching for エルフ耳 will exclude images only tagged with エルフ (which is most of them.)
When you find an artist you like, make sure you check their bookmarks. Good artists almost exclusively bookmark other good artists, typically ones with similar subject matter. Artists who draw touhou bookmark touhou, artists who draw elves bookmark elves. Follow the links, and remember the search only works when people actually remember to add the tags. I've stumbled across pointy ears while browsing galleries that I couldn't find when searching because nobody bothered to tag them with エルフ or エルフ耳.

It's tagged for World of Warcraft, so if the shield you're wondering about is from WoW, then probably yes. Of course, if you're thinking of something from a different game, then definitely not.
