ゆのみ (yunomi) is a female amateur arist from Japan who is extremely popular on niconico for her contribution to many notable Vocaloid songs, particularly magnet and Just Be Friends, as well as Cendrillon and the fan PV for コンビニ (KONBINI/Convenience Store). Prior to making her break with Vocaloid songs, she was also very known for her 魔人探偵脳噛ネウロ (Majin Tantei Nougami Neuro) fan PVs. yunomi’s name is an shortening of 湯呑み茶碗 (yunomi chawan/teacup rice bowl) even though they are two different words. She also seems to like drinking coffee from Starbucks, and the PC she uses is white.
yunomi’s style is usually very similar to the traditional shoujo manga style, with long necks and limbs, big eyes and mouths, and angular lips, noses, and chins when drawn in profile. However, unlike the typical outdated shoujo style, yunomi’s is a lot more modern, with well coordinated outfits and fashions (see image above), vibrant colours, and glassy, shiny eyes often seen in anime-style art today. As well, yunomi is extremely good at coordinating colours and touching up her drawings to make them look complete and professional, and the expressions she draws on her characters always evoke a lot of natural and sincere emotion, especially the wide smiles seen on a lot of them. yunomi can also be very versatile with drawing styles as you can see from her Neuro videos. I highly recommend watching the ベルばら (Rose of Versailles) one.
