Place to shout

This is the picture that I drew for my friend.

It seems to represent that a shining adorable monster is emitting a beam of light as hard as he can, the beam has not reached the right half of the space, though.

The simple message I got is below.

“You are shouting at the wrong place.”

However much he shouts or does his best at the wrong place, his light can never reach. He should be at the right place.
It says it is the time when he should move to the place he should be at.

In additional information, the adorable pink monster in the picture represents himself, but also seems to be one of his guardian spirit:)
