Tropical Tree Canopy Creation

I need help building a massive tree based on the “home tree” from the movie Avatar. i already have the trunk done and i have finished most of the canopy, i just need help making the canopy look natural, and adding branches with smaller canopies extending from the main trunk. maybe some long hanging vines made out of jungle leaves as well. i have attached an image to show what i am already working with. i am on play station 4 but i believe i can play cross gen with anyone. let me know who can help. i do not need you to do any interior decorating or furnishing, i am only looking to finish the aesthetic of the tree its self. i will turn the then finished tree in to the spiral staircase version from Avatar myself.
