Hi my friend. It's great to see you posting in REC. This is quite a difficult solo to attempt, especially as you've only been playing for 1.5 years. There are some areas where I can recommend that you focus on to improve your lead playing ability.
- Your picking hand. You seem to hold your hand in mid air so that it's floating above the strings.. this makes it difficult for your hand to be accurate. Try resting the side of your hand (the side of your little finger) against the strings, near the bridge, as if you were doing a karate chop. The side of your hand keeps unwanted strings quiet by resting against them. Also, having contact against the guitar body will help you stay accurate. You don't have to keep your fingers sticking out, you can curl them in like a fist of you want.. it doesn't matter. What is important is that you have a natural hand position that rests near the bridge of the guitar (near the tremelo system).
Have a look at the 3rd photo here

- Hand synchronisation. Your right and left hands are not quite synchronised yet. This lesson requires some alternate picking and it will be near impossible to replicate if you're hands cannot work together at the same speed. I would pick some lessons that focus on simple picking licks. I have a lesson designed to work on the right hand only for alternate picking beginners.

-String bending. This is a very important part of guitar playing so some work here is essential.
