Do you have beta or prototype versions of character designs that have changed from planning to production of your web comic?
I just found some old versions of character's from almost a decade ago and was blown away by how much some of them changed and how some of the old ideas evolved over time.
All dragons had their noses moved to the top of their snouts, feet and uniform changes. General Oleander had the biggest design change.
Prototype General Oleander Designs:

Oleander was originally a little older than the main crew instead of twice their age, and he was bald without a broken nose & less stripes.
Sirona stayed pretty much the same, but less angular.

Orion and Sagi went through visual design changes, but personalities stayed the same.

Final Orion and Sagi Designs:

Tabai and Tinge were based off of my Ranger Khajiit and Illusionary Pickpocket Argonian builds in Skyrim.
Tabai was a more realistic looking cat with the Thieves Guild armor from Skyrim while Tinge looked like a mix of Kermit the Frog and Leon Powalski from StarFox. They didn't fit from the digital vector art to watercolor background style change, so a lot of characters became more 'toony' to fit the style.

If you have any prototype to finalized character design changes you have, share them with stories about how the design changed over time!
