His world is literally created by a god, an entire subcontinent, Beleriand, was destroyed/sunk into the ocean in a war between lesser gods, then they raised and later sunk the island of Numenor and finally the continent of Valinor ascended into the heavens. In Tolkien's world this is not just myth, it actually happened. And considering all this your big problem with the world is that the continents don't look like they grew naturally (for lack of a better term)?
