I think the knuckle shading is excessive in darkness but correct in extent. This is personal preference.
What you've kind of drawn for the missiles is both the as-launched two-stage missile (shown vertical) and the free-flying second stage alone (shown horizontal). There's no reason that this shouldn't have been the standard (no pun intended) that we established a million years ago, but I think almost without exception, missiles and rockets are shown exclusively in their as-launched configuration. Note the Terrier booster aft closeout is aligned with the lower edge of the ASROC fins.
I've also added the nuclear depth charge version of ASROC, which was in service by 1962.
While I'm thinking about style things, the SPS-48 and SPS-29 are both very ancient parts (late 2000s, I think) and they could use some attention
edit: whoops, exported as a jpeg, but you get the idea. Nuclear ASROC is available on the wiki here:
