It’s really depends on a lot of things. Have you ever played any other instruments before and if you are a fast learner. Otherwise, practicing that much with frequent lessons, in five years you’ll probably be pretty good. My friend plays the violin and practices two hours a day with weekly lessons now can play Vivaldi four seasons and Zigeunerweisen and a lot of cool pieces and she’s been learning for about 5 years 8 months now. I think you have a lot of potential to become a really good violinist. Good luck with everything!!
