I know you've already chosen the icon and you're probably not looking to get a new one, but I just wanted to submit one I made earlier today.
It's a pretty simple icon, but it follows the Android design guidelines better than the one chosen. Not only that, but I feel my icon is more symbolic. The red piece that's being added to the rest of the icon symbolizes how the xposed framework completes Android (green) and implements modules that branch out to different areas of Android.
Any feedback and suggestions would be appreciated!
*also, this is just a rough draft. If the developer would like, I could continue working on it
