"In keeping accordance with 'whatsoever you do... do for the glory of God', how does one create beautiful, aka 'attractive' characters?"
It's a question that's been answered for many people over many hundreds of years. But people have different gifts, strengths, and weaknesses, and we have a new batch of people.
What is your conclusion? Do you even have one? What's your experience as a consumer of art with attractive characters as relates to the question? (Simply, do attractive characters in art influence you in a good or bad way?)
Let's broaden this even further by not merely focusing on the visual aspect of character design, but also include the person of that character. (i.e. an "ideal" character to the consumer)
To keep things straight, I'm not looking for an answer for me. I'm looking for your answer.
