Your activity looks fine to me, you have the recuirement of 15 hours of gameplay. Altough i would recommend improving your application information a bit as Morgan has already commented. Also this is not necessary but coloring up your application is a great thing to do. It makes your application look much more proffesional. Another great idea is to check other peoples applications and see how they have written their applications, make sure you dont copy anything though!
My verdict:
As i said, your acitivity is great but you really need to improve your application, thereby its a neutral from me. Good luck with your application!
