This one is made for a mobile game called Star Heroes’ Record (Temporary name), which is an RPG- Strategy game for iPhone, pad and Android. It haven’t been released yet.
I like them all except the messages one. It looks nice but I think maybe an ink brush and a parchment would've suited better? The current icon seems hard to remember and might get confused with "Task". Maybe you already thought about it and decided that the parchment would've been even more confusing... But this is just my opinion.
I can't wait to see this game
Oh and congratulations for the DD!
