I think I look at it a little differently!
In a way, I don't believe in ugly characters. I don't want to find any of my characters ugly. But I don't really think about it as "prettiness" versus "ugliness," I guess? I definitely try my best to create some characters that are outside of "my type," but when I'm creating a character, no matter what features or body type or age I give them, I want to make characters where I love every part of how they look!
And I mean, that includes characters like these guys.
I want a bunch of different kinds of characters in my comics, and I do work hard to learn how to draw different kinds of people -- and I have a long way still to go! But my challenge when I'm branching out and learning how to draw new features or body types or whatever is usually in learning to see all of them as beautiful. The first time I decided I wanted one of my characters to be chubby, it was important to me to sketch her over and over and over until I could feel really comfortable and happy with her body.
I guess I feel a big difference between making characters that might be considered ugly by their peers, and "making an ugly character," and there's something really cool to me about taking a feature I don't normally like and finding the beauty in it through a character I love. I think you can often tell by looking at a character whether the artist thinks that character is beautiful or ugly. Something shines through!
.......But, y'know, all that said, there is a character in Runewriters who is absolutely drawn as exactly the type of character I personally find attractive....... and it's the guy in red up there. So, uh. There's that as well.
