I was hoping for some help on what to do with two Japanese Buxus I have.
The first was one of my first go at buying nursery stock and trimming it down, although after seeing more on here and reading all the rules and guides for Bonsai on the wiki page it appears I may have been way off the mark! Would it classify for a broom style?

At the time I thought it looked good but now after learning a bit more it seems there are too many branches and no main trunk line?
What would your suggestions be on the best way to clean it up a bit?
This second one I got for a steal when I purchased a Cedar last week, as soon as I saw the nebari I had to have it.
I'm unsure what to do with this one as it has two major branches splitting straight off from the trunk

I've included a close up of the branches.

Any input to stop me from making further rookie errors would be much appreciated!
Thanks, Chris.
