Leaving it alone for the time being while you learn about it's horticultural needs, and some bonsai basics will IMHO give the tree a better chance at thriving vs. living thru prunings, pottings,and other styling efforts when they shouldn't be done. I applaud you for the restraint you chose due to lack of knowledge about your subject, check out our beginners section, the articles, and this website -
