One of my hobbies is dedicated to several personal stories, stylized as a graphic novel or an illustrated novel. Made in 2012 and 2013, I felt a sort of branding was needed for each one and so I tried to make a title logo for both.
One was themed around adult subject matter: sexuality, love and the struggles of young adults in their relationships. I wanted to incorporate the title into a heart shape.
The other story was a fantasy based story, using mythological an religious themes together. The audience was for older teens and younger adults. The aesthetic of magical keys, locks, and doorways to other planes is used heavily in the story and so the title and logo was designed to match. Unlock's logo will probably have the font updated, with the lock (The "U") remaining somewhat the same.
