Hector,
From what I can make out in your picture, you might have a blue rug juniper. It is hard to tell for sure. Blue rug junipers and California shore junipers don't lend themselves to bonsai. If that juniper were mine, I would plant it in the yard and find a better subject to practise on. I suggest a "procumbens nana" juniper. Also known as Japanese Garden juniper and squamata pastrata (not sure of the spelling on that last name). The nana juniper is ideal for practising on and you would be able to see results for your efforts pretty quickly. They are readily available at most nurseries and big box stores like Lowe's or Home Depot. I hate to see you waste your time on a variety of juniper that is going to "fight you" in your efforts to style, to grow nice "pads" or branching.

That is just my opinion. Good luck with what ever you decide.
Best wishes.
