Nice job, Secret Identities is a great idea and well done banners!
On the other hand, head banner on 'a certain other form of social media' ;) feels too heavy. I'm also not a fun of overusing colour gradients, especially in logos. Gradients make it more difficult to keep visual consistency. For example sign shops may have problems with prints. Flat designs can be also cut in self adhesive foil / film, what is also much cheaper. Gradients may also cause major differences in how design is displayed on different screens and in different lighting environments.
Overall good job!
Thanks for the detailed feedback!
Couldn't agree with you more on the gradients, honestly. All of my original designs used flat colour, as that is my preference, but this was pushed in the current direction through collaboration (and compromise, I suppose!) with the wider requests of the community.
Ultimately - I very much imagine we'll see single colours used in some applications and I have colour codes for that eventuality :).
