Quick pruning and root correction for my ficus benjamina

This ficus is from a cutting I first grew in a tiny pot but without daily caring, it was difficult to keep the tree healthy so I decided to put it in a bigger pot and grow the tree as a mini bonsai. You can find the videos I first planted the tree from a cutting from the links below:

In this video, I will prune some of the branches and make corrections for the aerial roots to keep them from thickening too fast compared to the trunk so the tree may look more miniature.
Thank you for watching!
