Pretty Fly for a Bonsai Guy
The trunk on your pine will never become a formal upright trunk, which requires it to be arrow-straight and tapered evenly to the top. Even the pine in your post above is arguably not a formal upright.
You'll get some back-budding, and it likely has buds close-enough in to work with.
One significant challenge with your pine will be the uninteresting trunk section between the Shari and the first branches. Another challenge will be to deal with the knob atop the trunk from which most of your branches emerge. The good news is that you'll always have foliage to hide flaws behind.
I know material is difficult to come by in your region, and unfortunately, this tree wasn't very well grown. You're a young guy, you should be growing this stuff from seed. In a few years you'll have much better stock to work with.
