Particle and BGM

Hi, now I'm going to build a stage where anyone can enjoy karate animation for long time by loop long animation.

This space will be completed after about 2 weeks.
I want a large fire at the center of the space. So, I began to make it by particle.
The image below is not the space, it is my private laboratory.

I have already set up the BGM, please hear it if you have a time to go my shop.
