It's hard to say that political fantasy has its own writing style. However, as I write so much of it, I have come to use certain expressions which seem to fit especially nicely in describing other polifan works, as well. Here, I take the broader meaning of sensual as appealing to the senses, and the broader meaning of intellectual, as appealing to the mind. Intellectual writing style can be found best in the passages of witty banter which all writing sports now and again, but which seems especially prevalent in political fantasy. This is about the twentieth person today who hasn't recognized me.
Witty banter is only the half of it.
It might be said to be the best combination of intellectual tools. It includes anything which relates to the reader at a gut level. Symbolism, description, and action scenes, then, are probably the best tools of sensual style. And, as soon as I find an excellent example of a sensual passage, I will put it up here. Combining these elements is the fun part.
