This is an awesome boxwood(Buxus harlandii) belongs to a bonsai buddy in Kuching.
It's old enough, with good nebrai (floating roots), very good cork bark stem and branches. And how I wish I can have a material like that!

With his consent, I can post it up here with my suggestion on how to improve it's look.
My suggest is that to work on the foliage first. Changing pot will come later.
An extensive cut back is actually required to allow to grow back before shape.
Hopefully the following can give the basic idea how to do it.

Cut become botak, something like this.

Then allow it to grow back for 10 months to a year, feeding it with a little fertilizer once a month and water everyday.
It will grow to becomes thick mushroom shape bush, something like this.

       

Then cut away the small branches and expose the stem and inner part of the branches.
Trim the foliage canopy and let it grow for another 6 months or so.

This time beside trimming the foliage, choose the branches  that you think that's not suitable to cut away.
By then it should have become quite awesome something like this.

Hi ichiglance,

The specie you have is called Feroniella Lucida. It's a terrible thorny specie that even the thorns at the young shoots can hurt your fingers.
Not many people like to train this specie to become bonsai. I've this one growing at the edge of a low rubble wall but yet to have any intention of shaping it.
Although this specie is thorny, but it's foliage(leaves) has the characteristic of  natural flat shape.

As for your Lucida, it has a good old looking big stump. But the branches have grown very much out of order.
My suggestion is to cut and let it re grow and guide it in the shape you want with wires.

The idea is something like the following photos down loaded from the internet.

You can go to google, search for " Feroniella lucida Bonsai" to look for bonsai images that you think you can follow.

Take care your your fingers buddy, when you are working on it! 

Oh oh! No. The name is Bonsailelong.

HAPPY N PROSPEROUS CHINESE NEW YEAR!
