Phylogenetic Tree

I compiled every plant I currently know and am able to recognize onto a mostly correct phylogenetic tree (I think).
Im a 20 years old french landscaper and have started learning about plants last year, and I wanted some feedback on my work. Its still a work in progress, and I update it almost weekly.
I'd love to try my hands at actual botany as a profession one day, do you guys think that's unrealistic?
