I'm really new to bonsai world. This is my first ever attempt to style a plant.
Is it really the first time you wired a plant? If that's so, that's amazing. Your wiring is not bad at all, much better than what we see from other first-timers on this forum. Looks like you've got talent. The shaping...not bad really, but I think you removed a bit too much and you should have kept foliage closer to the trunk. But again, for a first-timer, not bad.
Any suggestion and and warning is very welcome to improve my technique
My tip is to ask for suggestions BEFORE wiring/pruning/shaping the tree.
Also, I wouldn't have selected a Picea. They're not easy to train.
For now, I'd not do more with the tree, just give it proper care and let it grow. Most important is to keep the tree alive.
