I'm absolutely new to bonsai and i really wanted to give it a go. I bought a trident maple and i have no idea where to start. I've looked all over the internet and i can't seem to piece all the information together for my particular tree.
Here it is:

Should i prune it? and how?
Is there anything i shouldn't do when pruning?
Should i re-pot it?
And any information you can give me would be very much appreciated.
I really like this style of bonsai but i know thats a bit ambitious at the moment.
