Journey to the past n. 1

Hello mates, I am vacationing in Italy and as I was looking for my secret stack of watercolor paper... I stumbled upon some veeeeery old stuff.

Okay, expect horrible drawings, you can tell by the paper, so thin and yellow, that these drawings are more than 20 years old.
This set is from 1990, they were initial studies for some of the scenes that you already saw in the Pirate Balthasar.

Let's see if you can tell who these are and what's going on (except the one with the child that was only used for an illustration).
