1. For the podcast I strongly suggest interviewing Ethan Van Sciver. He's an amazing artist known for drawing a lot of the important Green Lantern stories written by Geoff Johns. Such as https://en.wikipedia.org/wiki/Green_Lantern%3A_Rebirth
He has a youtube channel "ComicArtistPro Secrets". https://www.youtube.com/channel/UCp8nOGQKLpFhtoIOOUVK40g Based on his youtube channel, I bet he would do it. I'd love to hear you talk about art with him. (don't be fooled by the fact that a lot of his recent videos are about Disney destroying Star Wars.)
2. Another very interesting topic would be Web comics. I'm talking sites like Webtoons https://www.webtoons.com/en/ , and Tapas https://tapas.io which let people upload their own comics.
Thanks so much for these great suggestions! Really appreciate you taking the time to give us some ideas for future Podcast episodes. I'll get in touch with Ethan and see if he'd be up for joining us on the show.
