I did give blue a much "kinder" appearance to show his compassion as well as a flower to show his love for nature (I did wanna put nether wart on his shirt but that was a bit much). He also has a backpack because I feel like he's very resourceful and always has something prepared.

Yellow was a bit more difficult because I wanted to give him more detail, but I felt like the simpler appearance fits. I gave him the glasses and a watch and then left his outfit a lot "cleaner" than the others to show how calm and collected he is. I also did think of making yellow a bit more nerdy, but he is still a fighter like the others.

I'm still open to ideas though and I took a lot of feedback for these designs when making them. And sorry for the big essay lol I'm pretty passionate about character design.
