☞ Bring your beloved Walkman™ back (Icon) -
where you will also get most system/Home apps + most commonly used apps (like browsers, Gmail, Google, WhatsApp etc.) icon with drop effect in order to match the theme style
✔ Supports devices running KitKat to Nougat
✔ No root needed
---------What's tried to give it quite different look---------
◇ No more plain color on status bar, which makes it little unique while day to day use.
◇ Created a clean transparent clock over Lock Screen to match with every lock screen used or album art (for Music) displayed there.
◇ Backgrounds to match theme, unlike much plane background or too bright/whitish background (App background)
Though such changes may taste different, according to the flavour one likes ツ
So...try it by yourself.
* In case if your phone doesn't show theme's effect (like-applies only wallpaper, as happens on some phones), then try setting-up any default theme and restart the phone & then apply it, or try the same with re-installation.
** Some of the theme elements may not work (or look different) for some devices or android versions, for the best support at-least Marshmallow is recommended (or Lollipop 5.1).
For example- Theme's Lock Screen Analog Clock, Home Clock color or Icon changes (Drop effect on Home/System Icons) is only supported to Marshmallow or some devices running Lollipop 5.1
