So i got this plant today (Japanese Black Pine)

Its 3.5 years old, grown from seed.
My question is.... What now? Ive read many book and stalked the forum here but i only know how to maintain and 'grow' the pine. How do i turn this into a good Bonsai to begin with? I cant get my head around how i can promote more branch grown and/or bring the growth back to the center of the tree...
I know this is a bad question, i actually brought this tree to plant and have as a seed tree many years down the track (im only 25) BUT now i have it i figure i may give it a go. (if it is do-able) Its really what i want to do anyway...
Any advice would be great... I do have a specific Black Pine book on the way which should answer most questions. But what should i do now?
Thanks guys
