Profile picture for youtube channel with the Animal Crossing villagers Marshall and Erik with wintertime clothes and cozy theme with matching banner

I'm looking to create a profile picture for my YouTube channel featuring the Animal Crossing villagers Marshall and Erik. I'd like for them to be wearing wintertime clothes and I'm aiming for a cozy theme. Additionally, I'd like a banner to match. The style of the picture and banner should be illustration. I have a few ideas for color schemes and elements to include, but I'm open to suggestions. As for text/branding, I have some specific requirements, so I'd like those to be included. The whole project should have a wintertime, cozy feel. Thank you for your help!
