Technical Delay: "Null null's commission, final part"

Dear fans, old and new, greetings from your giant creator!

Dear fans, old and new, for those who don't know, I remember our next commissioner: the longstanding fan, null null.
His commission is simple, yet brilliant, depicting a very familiar scenario: the mega giant wrecking havoc in a puny (papercrafted) city.

The story is simple, but exciting: after workout, a normal guy (yours truly) starts growing uncontrollably, reaching majestic proportions, while wreaking havoc on a unaware city.

Unfortunately, I have been dealing with some technical difficulties involving how badly the flood effect comes off in the final export. I have been dealing with some solutions to work around the problem.

In the meantime, stay tuned!

Yours truly gigantic,
