I didn’t think it is any “bonsai style”. But why fit into a Japanese category? The tree you pictured (I like it btw) looks like something Harry Harrington would have on his bench. Just a nice naturalistic type tree. Not dynamic but peaceful and familiar looking.
Everyone has an opinion of course but, I don’t think it’s necessary to only produce/purchase trees that look like the “bonsai styles “ page of those beginner bonsai books. If you want to create one, great. Or buy one, awesome! But don’t force something to be something it isn’t.
