you need to let this grow for years (unrestricted both in root and leaf growth- like not prune for that time), apart from a root prune. Put it in grow box or ground, or you will still have a stick in a pot, as you get no girth in a bonsai pot.
Salut l'ami,
Maybe there are solutions that could possibly fit better in his environment.
From the photo he posted, I think that Silverio doesn't have much room to grow "big trees" .
@SilverioSan :
Keep it healthy, it's a nice tree.
Hard to give you much advice for I'm lucky enough to have a garden, and keepind a potted tree on a balcony must be a totally different thing.
But if you take good care of it, in time it will come a nice bonsai.
I'd say you must find "akadama", or a similar medium before you repot it : the best soil you can find that is adapted to various climates. 75 to 90% of a mix with any amount or combination of composted bark, pozzolane (good for the roots to divide), coarse sand, peat fibers, coffe dregs, old leather shoes, etc.
In a wider pot, you could use guy-wires to have the branches bend down in quite a natural way.
Anyway, whether conform to the standards or not, you will enjoy its colours, every day
