Hi, this time I was trying to play a little bit with particles and lighting in order to create this kind of specific atmosphere. When I looked at the final render I realized that it looks like the place was on fire. That was not initial intention, but I decided to leave the decision whether the place is burning on viewer.
are those fireflies or particles ? 
Initially they were meant just as meaningless particles to make it look more interesting, but they can actually be whatever the viewer wants them to be
