Struggling 4 Year Old Sycamore Rescued | Repot | Bonsai

I collected a Sycamore seedling 4 years ago and potted it up. It's been in the same pot with the same soil all this time and it started to struggle.
The problem was with the soil. It badly needed a repot.
In this video I take the tree out of the pot, rake to the roots, wash and trim them with sharp scissors. I then repot the tree in the same pot but with fresh soil that shouldn't suffocate the roots.
Hopefully the tree will thrive and become a nice bonsai one day.
There are of course things I could have done differently, making better choices earlier like grow it in the ground for better thickness, but I didn't. It is what it is.
Thanks for watching
