Probably there is an imperceptible touch of something permanent that one feels instinctively to adhere to true humour, whereas wit may be the mere conversational shooting up of "smartness"--a bright feather, to be blown into space the second after it is launched...Wit seems to be counted a very poor relation to Humour....Humour is never artificial.
I notice that you use plain, simple language, short words and brief sentences. That is the way to write English - it is the modern way and the best way. Stick to it; don't let fluff and flowers and verbosity creep in.
