I interpreted that part as ironic, i.e. “just learn to draw you can do it too” isn’t exactly some insane revelation, so making it advice from superman is probably meant to ridicule the idea that being able to draw is some godgiven ability (like supermans).
Also self inserting as superman is kinda wild.
It assigns such a high authority to the speaker that it immediately comes off as pretentious/corny.
