Hi everyone!

I've been trying out new styles lately, so I invested in nice pens and got a map up where there is a chamber of shallow water and a deep end where some lost creature has made its lair.

Okay, I'm busy with the color version and it is turning out nicely, but what I need help with is what I need to place on the map. As I've never played a tabletop RPG but really enjoy listening to stuff like Critical Role, I'm still a little bit in the dark. I've only done a very few battlemaps, and don't really know what objects to place around certain types like this one. I would like to hear what you suggest for this map. Also, I tried a grid for this one, 46x34, is that too big or what is the average?

I want this to be a fun map for people that play these things, so I'm looking forward to your suggestions.
