Hi Delalaym, and welcome. I'm pretty much a newbie too, but here's my

worth. It's your tree, so it's up to you what you do with it. A broom style would certainly maximize the flowering display in season. I do the same with a couple of mine. My better half likes to have flowers in the house, so I've got some bonsai that flower, and I bring them inside when they are in flower. I don't worry too much about their "style".There is no rule or law that tells you how to style your bonsai. If you wanted to show it or enter comps with it, that's a different story. You would have to adopt one of the accepted styles suitable for azaleas.
Good luck with it.
Frank.
