Welcome to bonsai.
The wiring looks quite neat apart from a few crossing wires but more practice will help you work out how to plan to avoid that. No before pics so it is hard to assess how effective the wiring is. Wires don't make it a bonsai. They are just to help change the shape so not needed unless change is also needed. Many beginners just wire everything for the sake of putting wire on.
A couple f the branches on that juniper look very straight. Withe the bends in the 1st branch I would be following that with some similar bends in all branches for consistency of style and design.
You will surely get a range of opinion on how appropriate it is to style little, skinny trees like these so be aware there are many ways to develop bonsai and a whole range of standards of bonsai. Most beginners start out with skinny little sticks which usually gives us some good practice before graduating to growing trees with some real character and decent trunks.
You need to be aware that trees in small pots really slow down growth and development so these are likely to still be little skinny trees in 5 years. Many of us routinely develop our trees in larger grow pots or in the garden to get faster growth and only move trees into bonsai pots when they are well developed. I think it is worth getting some more trees to go in larger pots for future projects. That way you have the satisfaction of having a couple of 'bonsai' but also have some more potential developing for when you are ready to take the next steps.
Also be aware that, thanks to the WWW bonsai nut has readers all over the world. It is really helpful to add a location to your profile so others can modify advice to suit your particular local conditions.
