Questions & Mysteries does the mural depict silhouettes?

[Bisoromi Bear]

Something has me thinking...the Gorosei were depicted as similarly looking monsters when Sabo saw them, but those were just their silhouettes.
Are the black monsters depicted here silhouettes too or their full appearance? And what about Imu?

We have seen before that Oda can draw entire chapters showing a character and simultaneously not actually showing them, only their silhouette.

Thr "Gorosei" may have been different st that time, if I had to guess they are those 5 on that ship besides the monster where they face towards Joyboy and others

Imu may be the three silhouetted characters, the small one with a crown on another ship, the serpent with wings (zoan form) and the hybrid form on the left, all 3 having in common being as the only silhouette's not even scribbled drawings

Not even the humans on the mural look like humans.

Those are just scribbles.
