Okay removed all moss and rocks. The soil is damp on top so I would probably say the soil that the plant is in isn’t fast drainage soil? Should I repot in new soil or leave? I haven’t watered it in about 2 days.
It is a common mistake that you need fast draining bonsai soil for plants like this. Fast draining soil, proper watering and fertilizing are three bonsai techniques that cannot be seen as separate. You will need to learn all these techniques.
You do need a soil that drains properly though, it must not stay waterlogged.
Your soil looks OK to me. Do not repot, it will stress the plant even more.
Give it proper care - which for now means proper watering, the right position including enough light. Don't fiddle with it. Give it time.
Do read up on the care guidelines for your species.
