Good job for just 2 years of experience! You are doing a lot of things really well here and although you are nervous–it doesn’t show that much! You have the right to be more confident as most students at this level wouldn’t even post a video–keep up the good work!
Regarding some suggestions, I would first like to give you tips about your left-hand. When you play on the E string around :44 your hand totally moves to find the F natural. What you should do is setup your hand farther back so you can hit the F without having to adjust the hand. This will help your ability to play faster and more in tune. I suggest watching these videos to help you achieve better fundamentals with the left hand:
Regarding your right-hand, there is a lot you are doing well. I would suggest using more bow in general especially when you are crossing strings. Try practicing scales slurring two notes per bow and try to use the entire bow from frog to tip. That is a good exercise to build better muscle memory to acheive a more powerful sound. Hope this helps!
