It looks really good :)

Maybe adjust the positioning of a couple of the ocean names just a little to prevent them getting so close to the land? And that Blood Sea label is pretty unreadable as it stands. Maybe it's one of those rare instances where you need to break the rule about the blue ocean labels and turn the label for that one a very pale blue - quite close to white? I wouldn't make it absolutely white, though, because it would stand out too much.

Maybe the key should be to one side or below the whole map, since there isn't a lot of room in the map, though it's really too early to be thinking of the key. It's more of a labelling process at the end of the drawing.

I can't see what style you are using because it's so huge the textures are too small to identify, but the answers to some of the other questions could depend very much on the style and the arrangement of the sheets.

If there's not very much happening between the points of interest, you could do several dungeon scale maps - one for each point of interest?

Don't get caught out by failing to check the time. This livestream is an hour later than usual.

There is a pink glow on the SYMBOLS CLIFF sheet. I've hidden it in this screen shot.
