That’s a great idea, I hadn’t thought about it that way.
If you know any influential figures here or have photos you think would work well, feel free to share I’d love to turn that into something impactful.
Discussion
While your characters are all fantastic, they're not familiar to this audience. You need to draw some well-known figures. Because they're familiar with the people here, they can immediately compare how realistic your drawings are. This will allow them to more directly appreciate the exquisite skill in your art.
Thank you for the feedback.
