I'm about to wire this small juniper I got. Any recommendations, or suggestions. I can't really see a shape in the tree apart from cascade which I don't fancy at all.
The reason you can't see any shape is because it is too small to have a shape. It definitely needs to be grown to get a more substantial trunk so there is something to work with.
Junipers are prized for their wild, twisted trunks and dead wood but in captivity with gentle conditions they tend to grow tall and straight. I start wiring junipers when they are really small and thin and bend all sorts of tight twists and turns into all the trunks and branches. Don't worry too much about style or shape at this stage. The whole tree will be completely different in a few years. Just try to get random bends and twists. Try to avoid regular corkscrew bends and straight sections, especially near the base. The smaller the final bonsai the tighter the bends need to be generally.
Don't worry too much about taper at that stage. Most of it will be cut off later anyway. Leave as many trunks and branches as possible because every bit of live foliage will contribute to growth and thickness. Junipers are slow growing so you need all the help you can get.
Jinning thin branches is a waste of time. Matchstick jins like you have made do not look impressive and most will rot away before the tree has developed enough to be a good bonsai anyway. Use the extra branches to get growth.
Transfer the tree to a larger container or into the garden for a few years so it grows at maximum potential to get thickness quicker and then work out what to do with the results in 3-5 years, maybe 10 years if you want 10cm trunks like the ones @Rivers Edge has posted.
