I am a fan of Rarible site too. The seriousness of it and its graphic association to ‘tech’ and ‘computer science’- a very Web 3 trend: https://rarible.org/
Our difference I would say is colour. We want a brighter, more radiant look to reflect the other platforms. But the seriousness and Web 3 ‘feel’ is important to integrate.
To add to this, we dont want it to feel too ‘computer science’, but can leverage our association to collectibe cars by using some serif fonts in conjunction to more web 3 ones. This will mix traditional ‘seriousness’ to new web 3 tech. The combination of which is the ‘feel’ of old world and new world. This is only slight, barely noticeable.
