Hello Georgios! These characters are so cool~! It looks like they'd have a ton of fun adventure. The one thing that stood out to me was the character on the far left. His head is significantly larger than everyone else's, and though I get that he's a big character, I think if you made the head size a little smaller, he would fit a little more with the rest of the group. Right now it looks like if he was scaled down, he would have the same proportions as the character to the right of him. If you made the head smaller, it would make the rest of his body look bigger in proportion, similar to what you did with the character on the far right. Just my two cents! Thanks for sharing this fun cast of characters with us!
