Hey, thank you so much for creating these! We are using this for a virtual hackathon-style event called the 'AI Sports Challenge' (page here). I also really loved the art style and so have been using the images themselves in our marketing. Hope that's OK! Once we launch our full page with details I definitely want to credit your amazing work :)
Hey! Thanks for using my graphics. Looks like a cool event, hope it'll be a great success (but not too much either, don't want Skynet around just yet!).
Sure, you can use the graphics for the marketing.
Also: I've noticed that some people recolor the characters to make them their own - probably it's a great option to make them stand out a little bit - just throwing ideas : )
