@warandpeas my attempt:

1st panel:
A king exclaims (we know it's a king, because he has a beard and a kingly cape, plus he's standing at the top of a castle): Behold, I have built this majestic fortress.
2nd panel: slight zoom out. Besides the king, a servant (or some kind of wizard? They have a pointy hat) answers: But my lord, your castle is made of marshmallows.
