Found this at Lowes ( yes Will , I hear you ).
Lol, I am an avid believer in finding good stock where it is and make no claims that the box stores are useless, in fact I have defended them on this very forum. I also occasionally crawl through the big box isles. The mugo below was purchased for $4.95 at Home Depot. (yeah, the stone sucks)
One thing you'll find out about spruces is that they like the direction "up" and will always fight to remain in that orientation. That shouldn't stop you because they do make interesting bonsai. Vance Wood has a Blue Spruce that is remarkable (it took best of show in our club show this year) and that tree has always been my favorite since the first time I seen it.
It is very hard to see what is inside that Spruce as the foliage blocks the branch structure and trunk movement. Is there a way you could open it up and possibly scape a bit of the soil off so we can see the Nebari?
At first glance I would venture that you may have been better off by leaving all the branches on the left trunk and eventually getting rid of the trunk on the right. This would have left you with a good truck base and a trunk with movement as well as decent taper. This trunk would be far easier to wire and bend as well.
Even as a twin trunk, the left trunk would do well to have a lower branch on the left side.
You may consider in the future with stock such as this to leave all the lower branches instead out cutting them off. They would serve a sacrifice branches, thickening the trunk until such time as the design nears completion.
