Ok, I have two violin requests. the first one is a little weird because it's not a violin. it sounds like it might be a guitar but i'm guessing it's a japanese stringed instrument
Song: Higen
Anime: Haruka naru toki no naka de
The second violin piece is a little complicated because the song is a 4 stringed piece but the violin does carry the melody
Song: Tranquillezza for String
Anime: Ouran Host club

The third piece is for the piano piece. Overall the song's a piano piece but in the middle there is some orchestration. it shouldn't be too bad though.
Song: Tender Words
Anime: Meine Liebe Wieder

If any of these interest you pm me and i'll send you the mp3! thanks!!!!
