Aww this was so cute. I'm not gonna lie, how you did the 12 year old art work hit wayyyy too close for home, especially the detailed tragic backstory! But I can clearly see the way the art improved and progressed but the difficult part for the growing artist was attaching meaning to their artwork and what it means to them and the story. I couldn't help but really connect with the 24 year old stage where Galatea was more of a concept, something that had to change continuously but the way he changed felt forced like he couldn't settle down. I think it encapsulate the anxiety in young adults who have to find what direction their life is, and to be more mature and "adult-ish".
But that it quickly turns on its head when we reach 27 years old where we see the username for Galatea returned to the 12 year old stage but this time, Galatea has changed very much. But instead of there being this consistent need to change or to find yourself, the story has a sense of completion as Galatea works to find a home for himself away from the things he grew up with but still kept comfort in.
It makes me think back on my own OCs. Unfortunately, I haven't drawn in so long and their stories have slowly been forgotten, but I've been looking back on each of my art pieces to bring back the spark and reason why I even draw at all.
