Here is my participation in the "Mini bonsai Trees" contest, on Lego Ideas: https://ideas.lego.com/activities/c8d3ee66-86f9-4e3a-934d-acae9b5a491a?query=&sort=most_recent
Goal : to produce a bonsai with only 15 parts !

Everything revolved around the minifig hair part, which I wanted to use to make the vegetable ball for the trunc of the tree.
Afterwards, it's just a series of different pieces that give a more or less natural shape.
I'm waiting for approval ;)
