Found this link some time ago--has free downloads for some nice pieces to work on--
Characterize people by their actions and you will never be fooled by their words.
10 wonderful Violin Concertos, as well great play-along tutorials with at least 2 free Ebooks of sheet music, if you subscribe.
I prefer the tunes included in the 2nd Ebook I listed.
AND, I LOVE "Rieding's Violin Concerto in B minor, Op. 35"!
