Oh man, I totally see Ry liking a specific color pen and then fighting people over it when they "borrowed" it.
Great ideas! I do believe the physical appearance of the character is too important to leave out (I hate it when writers "leave it to the imagination." No, I want to definitively know what the character looks like!) But the "I woke up and looked in the mirror" trope gets old fast.
Your villain plays the most important role in your story. Yep, more important than your hero. That means you must go beyond the cliches when developing your villain, because generic platitudes such as maniacal laughter, minions and monologues are standard
