Happy new year.

I picked up this Mel as I just love the flowers etc. It was originally going into the garden but I wondered about bonsai. It is a dwarf variety so won’t be very big.
Would it be a struggle for a newbie? And if it’s possible to bonsai it, should I remove the bar branching now? There already appears to be some bulging at the joints. Not sure the best time to chop a little native like this, if at all.
Many thanks,
Steve
