Really good cover
The only thing I can knock on this song is the chorus and chorus buildup. The vocals were a little late and flat at times nothing to discourage you though. I like the sound of your voice and you have the feeling of Dave Mustaine. The solo is almost dead on. Just listen to the original for the timing a little closer and you'd nail this. For what it's worth, the parts you went flat were usually during the pied piper and the held Destruction....
Still a solid effort, keep up the great work and I will be checking in to listen to more.
