first of all apologies if this is the wrong place to post this.
anyway, acquired an olive bonsai the other day. my first bonsai

I'm thinking it needs a bit of a trim though? one branch is quiet a lot taller and longer then the rest of the plant, so feel as though this should be trimmed back? and maybe some of the leaves on the bottom part of the plant could come off?
im not sure though so any help/advice would be great

cheers
