High End Keynote Speaker seeks creative design for use on Book Cover and in Keynote Speech

C'est ce que Tip Jar Culture or The Tip Jar Culture recherchait dans leur logo design

I need a logo designed for a keynote speech that I'm currently turning into a book. The talk is called "Tip Jar Culture" and it's about how my time spent working in piano bars can be applied to making ordinary work environments more engaging experiences. Right now I have a very generic thing I developed on Canva, and while I don't "hate" it I also don't love it. I'm open to ideas and interpretations. This is going to be used in big and small places, so keep in mind it should be able to scale relatively easily (it won't be tiny like a favicon, but it will likely be used on a bookmark, for example). The less colorful the better, as I'll be using it in different contexts (a white and black version, both with transparent backgrounds, would be appreciated). Voir plus
