Oh boy do I gotta story for you
Alright so let's start with my sort-of "mascot" OC, Glitterpuff. I knew she looked different back in the day, but after digging up what I believe is the first-ever full drawing of her, well:
Her design went through many changes, though I'm pretty sure that soon after drawing
this, she started to look more and more like the one we know and love today:
Now for characters in The Four Friendly Humors; well... I'm a bit shy about those. This was back in 2018, and my approach to story writing was a bit different back then. Let's just say the humors looked a lot more human.
(Major cringe warning because I hate these designs (except for maybe Phlegm's))
SUPER big difference from this:
The new designs are sooooooooo much better in my opinion, not only because you can get their personalities more easily, but also because they are way easier to draw (and much more enjoyable too)
Also they look cuter.
P.S.: the concept of Sanguine being able to fly came from my research on humorism saying that sanguine was associated with the element of air. The idea was actually maintained for the entirety of pre-production, but then scrapped once I drew enough comics and realized that it would serve no useful purpose (if you look at the reference sheets I posted on Instagram, you can see the updated designs for his wings).
