Moby Dick is challenging for native speakers as well. Those phrases you have bolded are beautiful, but I don't think they lend themselves to easy images in your mind. Except the 'methodically knocking people's hats off' - what an image! That alone makes me want to reread this book.

It is true that many novels you can choose are going to be simpler than Moby Dick (or most books considered classics). You have such a wonderful grasp of the White Whale - I hope that you can conquer this book. In fact - conquering this book could even be your White Whale. Keep writing. I enjoy your style.
