Your contribution cannot be approved because it does not follow the Utopian Rules.

• Submissions must contain ...benefits of the work to the project owner.

• You said you want to make logo mor compatible with software content and name, but i don't see how your logo can represent the app functionality (programming lib for building microservices - JSON, HTTP, WebSocket, and REST)
• I found a fairly similar logo on the internet
  

Suggestions:

• The rules are updated, now graphic contribution is only acceptable if the project owner requested it, or if there's a proof that your work already used by the project owner.
