Concept art is really cool. I wish I could draw like that. Just putting a vision down on paper is really fascinating.
Well, but for a game jam game it's kinda overkill. Concept art is more something you do behind the scenes, or put into art books, or menu screens, or social media posts. There aren't many opportunities in a game jam game for concept art.
But I think what might work is using it for a title screen. I need to discuss this with our team further, whether we can actually have meaningful work for you. In the idea finding phase it's cool to have concept art, but for games jams it's a bit over the top.
Another thing is that we don't want the team size to explode. It's difficult managing a game dev team and the more people you have the harder it is to discuss things with the entire team.
Let's keep in touch and see what we can work out? Just hit me up on Discord. Dr Pixel Plays#9463
