The reason most of them aren't different is because I really see no reason to change them (except for the dark/electricity and light/electricity combos).

When I think of the word "shroud", I think of a choking black cloud, or even a living "cloak" of pure darkness. Cloaks are light-weight, hence the Wind attribute.

As for Nova, it was sort of a last-minute thing, but if you think about it, both light and darkness are found in the cosmos. When a star dies and goes supernova (Light), it can leave behind a black hole (Darkness) if it's big enough.
