Juniper Nursery ($13)

Hi, I’m a beginner and I wanted to get a tree to start planning for a bonsai. My local nursery got some junipers, which is weird since I’ve been going there like once a month for years and I never saw any junipers.
Anyway, I decided for this one and I had a couple questions. First of all is the price okay? Doesn’t make any difference since I already bought it but I’m curious.
Then, what would you do with it now? I plan on letting it grow but maybe someone experienced would recommend something else (like pruning).
Finally, I have some ideas about the future style of the tree, but I would love to hear some recommendations. Any specific style you would pursue with this tree?

Those are my 3 questions, sorry if they are stupid. I’m a beginner and I just want to learn.

Thank you in advance for your time!
