Looks like sort of an OK application to me but I believe you could have improved it a lot more in certain areas.
Firstly, I have no idea where you got the Server Playtime of "5 Hrs, 41 MIn, 52 Sec" (unless you have multiple accounts which you use. If yes, then please state them below). Your original Server Playtime, as shown, should be "2 Hrs, 24 MIn, 38 Sec" .You can check your exact playtime here :- http://xeno-gaming.co.uk/playtime/
Nonetheless, minimum requirement for the Server Playtime should atleast be around 1 Day or more (2-3 Days can be considered good).
Secondly, I personally have never seen you online on the XGC Discord Server. One of the prime requirements to apply for Staff is to be live and active on the Discord Server.
For the third question asked :- I believe you can provide a bit more than just saying that you are a reliable person based on no past examples or deeds. But I think this is up for the other Moderators and Senior Admins to decide on 🙂
I hope you can check these given points and make relevant improvements. In any case, good luck with your application. Enjoy and have fun on the servers!
