Hey, I'd like to design a logo for the Unity Community. Any guide lines you have in mind that I should respect? Some default size or something? Thanks!

You can take a look at the original awesome repo as an example for reference.
I took the glasses from these kind of repositories and included the Unity3D logo, but since it can't be used legally, i would search for any of the assets/projects has released during these years and use one them as a silhouette and then mix it with the glasses image if needed.

Feel free for the moment on the design and bring on ideas here or on discord and then we can give you feedback.
