I would not choose a style yet. If you want to go for a small tree, in accordance with the thickness of the trunk, the foliage is too far away from the trunc. So you will need to achieve some serious backbudding which will take years.
Second option: you want a bigger tree, in accordance with the foliage being far away from the trunk but then the trunk is way too thin. So you will need to fatten up the trunk which will take years.
I see a bonsai pot in the picture- you were not planning on planting the tree in it I hope? Not only is this the wrong time of the year to repot, the trunk will not or very slowly fatten up.
I would plant it in the ground , or a bigger container next spring, and depending on what your plans are chase back the foliage or fatten up the trunk.
