Minor changes to new armor trims

A couple minor changes to the new armor trims:

1: Add a bit more to the back of Flow's chestplate. Especially given how detailed the other pieces are, especially the helmet, it doesn't make sense to have a big empty space like how it currently does. My suggestion would be to add a square spiral pattern somewhat like the Flow banner pattern.

2: Brighten up Bolt's color usage. It only uses the darker few colors of each palette, which doesn't really need to be a thing that happens.

3: Add a couple more lines and/or dots to the front of Bolt's leggings. They just look so empty and they don't need to.
