You picked a nice trunk there. It has got good taper. Well done.
'Dwarf Alberta Spruce' is a cultivar, of Picea glauca, the white spruce. What distinguishes it from the normal form of the spruce is the vertical rising branches. The normal form of Picea glabra the branches leave the trunk more horizontal, and will descend with the age and weight as they mature. Black Hills spruce is a different geographic race of Picea glauca and also has branches that are fairly horizontal. Black Hills spruce is more heat and drought tolerant than the White Spruce and DAS, though all spruce like fairly consistent moisture at the roots.
Point of this is, going for downward, below horizontal branches with a DAS is locking you into a constant fight with the natural habits of the tree. You would have a much easier time of it long term if you chose to allow the branches to be at least a little bit above horizontal.
If you look, many species of pines, the branches really do rise above horizontal. You can have a very nice conifer, using your spruce to stand in for any of the many species of pine, and others that tend to have rising branches. You won't have to fight the natural habit of 'Dwarf Alberta Spruce' as much if you go with a rising style to the branch arrangement.
The way a branch exits a trunk is usually a uniform pattern for a tree. You have some that rise up, then "rainbow arc" down, you have some that leave the trunk heading down right away. This makes for an incongruous pattern.
You have 2 branches that arc upwards, candelabra style, in the spruce. One of the will become the new apex and one will become a secondary trunk. This actually is very "spruce like" in your design, looks like once they fill out they will be fine. They don't need to be changed. You can probably have up to 3 of these, and it won't look congested. At least at this point. Years later, they can also be jinned when they get too heavy, and new ones can be created.
So if it were mine, I would bring the branches to horizontal or slightly above. And work to bring uniformity for all the angles that branches other than the "Candelabra apex' branches should have the same repeating pattern of angle of insertion to the trunk.
But if you do decide to keep the "below horizontal" design to your branches, you will be locked into having a fully wired tree for all time. Even fairly thick inch in diameter branches will keep creeping upwards the minute you take wire or guy wires off them.
But I do like what you have done. You picked out a good tree. You were pretty successful at creating an image. The jin and shari are fine. And will take refinement well in the future. All you need to do is "clean up" the issue with consistent angle of insertion for the branches, and you have a tree well on its way to becoming a decent bonsai.
And it doesn't matter what angle you decide for the branches, above horizontal is the way I would go, but if you want to keep the below horizontal trend, just cleaning up the angle of insertion of the branches will greatly improve the look.
If some of the branches are too thick, resistant to bending, to fix the angle of insertion, you can wait for back budding, and then replace them with younger branches over time.
