Entry 18; I like the fact that "ALS Warriors" and "Wall Street" are proportional. I like the white ground. Prefer this shape to the one in entry 19. Entry 21: Like the emblematic aspect of the design, but "ALS" is the name of a fatal disease, and therefore the letters have to be in a row. Like the white ground, as opposed to entry 20.
Liking your colors...could try some dark purple as well, as this is the prominent color of the logo that will be the parent organization to the "warriors" effort.
