The level of thought and detail here is aweeeesome. I mean, who else doing growth sequences would take the time to think out all the spaces so accurately? For anyone reading this who does giantess, this is a challenge.
You managed all the box checks. You had a background to provide a reference point for the growth but beyond just that, you gave us a detailed bedroom that Nami's body interacts with. Definitely spoiling us.
That's the one. The concept is freaking awesome! I actually worked on some inking and coloring of one of those frames today. I'm not happy with what I came up with, though. There's just not enough detail in it for me to make it look decent.
