Quick question, could you either tell me the premise of how the character models were created, where they were gotten from, and how to create something similar to your used characters, because no other story's character is as good as yours, just my opinion.
It's the years of practice. Most stories devs hit "Good enough to release" and then stop working as hard to improve. You can see a huge difference between chapter 1 (2020) and 51 (2024), many other stories have had similar development cycles but the artists have just stopped putting as much effort into improving past "Good enough".
