雨 is one of my favorite too but when my sensei assigned me a Kanji for my name for fun, which does not have one since I’m not a Japanese, I started to love 令夢 (My nickname is Rem and this is read as Reimu) and has been using it as username, tags, IGN or whatsoever here in Japan.
香水 is fun. i mean, i feel like i have “aha” moments constantly, but “incense water” made me excited because a perfume is essentially an alternate process of scent composition with a different product.
