When I write, it comes out like this. Pulling your attention to and fro across a scene to construct "brain pictures", letting your imagination fill in the gaps as the fragments become a whole.

The mention of Megalosaurus was jarring. My imagination placed this within a gloomy late-Victorian period and the mention of giant lizard caused mental association to very unrelated content for the rest of paragraph. I think a Wooly Mammoth waddling up the hill would make for a better picture.

On another note: What are horse blinkers?
