I used the fireworks from GreasedLine as a poor man's particle system - #3 by roland with the tree from https://www.cgtrader.com/free-3d-models/plant/conifer/christmas-tree-76916a65-ba32-4dd1-a224-db98bb3280fc and a ton of clustered lights to make this cool christmas tree scene ^^
Sorry, I couldn’t resist looking under the Christmas tree 
, I was hunting for presents
