Haha, just fine. My thought was more, think about what you have in mind long term, and what you need to do to get there.
So, if you look at the size of the plant: The trunk is thing relative to the size of the crown. To make a believable bonsai, the final tree would have to be a lot smaller (Usually, a ration of 1:6, 1:12 of trunk diameter to tree height is used), or the trunk needs a bit of growing. Rootspread: Not able to tell what is it like. But it is something which can be an issue for trees that are really one-sidedly rooted. Then there is the overall age. The older the tree actually is, the more it will look old, most of the time.
So, from a species, Japanese maples are great from bonsai. The trunk is very straight and you indicate that is what you want. The individual plant you show is fine, but not great; It is like all other japanese maples for sal in this size. So no better, nor worse, than other JP. It is fairly young. So expect a middle long development process. Taking multiple layers from this tree will get you lots of material to 'play' with.
