I think it's time for me to give my Ficus a hard prune. I've had people tell me I should, but the problem is that I'm not sure what styles would work well for a Port Jackson. Can anyone help with any suggestions on styling?
This is the sumo fig that I purchased off of Dave54, and while I'm no expert, I think it's doing pretty well so far and I'd like to keep it that way

I'm a little nervous because I've not done any hard pruning yet, which is probably because I haven't decided on a style which would suit it. I've included a photo and warmly welcome any suggestions.
Thanks in advance!
