I’ve just started with a couple of bonsai’s, yesterday I repotted this one. Would be interesting to hear any ideas on how to shape or wire.

First things first: you didn't start with a bonsai, you started planting some young plant ( looks like a young spruce) into a container ...
Second, to answer your question, depends on what you want to achieve here. If you want a fat trunk, plant the tree outside, let it grow for a few years, cut back and repeat. If you want movement in the trunk you can apply some wire and make some bends.
In the little container it is in now it will hardly get bigger/ fatter ( it is a common mistake that a young tree planted in a bonsai pot becomes a bonsai. A bonsai pot is the last stage of training a tree and done to slow down growth and or reduce needle/foliage size)

This young plant could in a couple of years be a nice Literati. But I hope that you only took the picture inside and the tree is not kept there. I wonder why you felt that you had to re pot it. But now you have you need to be careful with watering and lay off the fertiliser. You need to grow it on for a year or two to get some branches to prune, in the meantime select which branches you need and which to remove.

You may also want to take a look at the soil you used and see if you can substitute some of it without hurting the tree. That looks like pure potting mix to me which will encourage root rot in such a small pot.

Rather not repot. This plant has just been repotted.
And.. Potting mix has been used for a while now to pot plants. They do not die because of the potting mix. THey die because of bad care. Root rot also, is not caused by the mix, but by bad care, in general speaking.
