hi mate
welcome to the forum firstly

you will find a great deal of info and help here
i dont think your tree is to tall, it looks taller with the short branches, you could probably take it back down and regrow the tree to give it more of a ration but i reckon it is in keeping with a full sized tree in nature except the buttressing that is normally seen on them, that does take a very long time to get that in a bonsai pot.
wouldnt mind to see a newer picture of it though

SHOHIN YAKUZA!!!
