Serenity - Sounds like a good intro!
Tension is sad, a little threatening and exciting. I like the way the strings complement the piano.
Welcome To My Abode - Sounds... Majestic!
Hey, you have a very beautiful accompaniment with an interesting piano part!
You shouldn't worry too much about the equipment. I am sure you will be able to use all the power that you have now, and you will do as well as this soundtrack! Good job
Thanks!
