There's certainly better detail in the 2021 version, but what really stands out is that while the original feels a little more expressive, both pictures kind of visualize your own artistic growth in a more subtle manner. Notice how 89 looks up and seems uneasy at the sight of a minotaur who has its chest puffed out and that pupil-less, godlike intimidation going for him in the sixteen-year-old image as opposed to the new one where 89 has a more rigid, confident stance while staring at a monster. It may still be towering over him (there's always more to learn) but the experience 89 has gained since 2005 provides a new outlook that makes his original difficulties with drawing seem silly nowadays.
I might be thinking too much about this, Tis.
