Guest post by "feral shade" hmm...and it just donned on me that perhaps the characters' refinement wasn't merely an improvement in storytelling skill
...but rather a planned development...illustrating how children mentally mature over the course of a few years (not something i normally consider, most artists have this annoying habit of separating story time progression from real time progression (like how the South Park kids have been 9 years old for the last 17 years...or Ash from Pokemon has been 10 since 1998)
either way, character aging or artistic growth, it's really admirable ^_^
