Good job. Learning any instrument is an accomplishment. Performing a concert is a huge accomplishment whatever music you play. You will progress quickly. Keep practicing and keep it fun. Play what you like and what makes you happy. And don't forget to try composing some music of your own. Just play around with your violin and try making up some tunes that sound good to you. Keep it up. And, a great way to learn even more is teach someone else...help a newbie learn what you've learned so far. Music is the greatest thing on earth!
