I’ll post a few other pictures in the comments, but yeah, this is the best I’ve been able to do with bonsai, this is actually not a tree but a succulent (Crassula ovata) which grows like a bush and can be used for beginners since it is really resistant to stress.
I would recommend you to get a Protulacaria, which is very similar but it makes a better bonsai IMO since it is more similar to a tree than the crassula ovata since its leaves are thinner but resists stress just as well as the crassula ovata does.
