No offense, but it doesn't look like it has been worked for 8 years, it looks like a 1 gallon home depot juniper drastically cut back and plopped into a pot. Not even sure it a procumbens, think those have needle foliage, but maybe im wrong.
I agree that one of the branches should be cut off. Perhaps wiring one of them and adding some movement. Also might try to clean up those roots.
Half of that slingshot needs to get cut off.
Either can be used, but then you get to design whats left.
Unless you go two line. Apex and cascade.
