When starting at the bottom of anything you dont do what you like but do what the bosses want, so ask for a job, say "i want to make skins, that meet your vision of a realistic server, this is a few ive done before".
Saying that, if you want to improve the community but don't know what to do, be like me, just be pleasant as possible to our fellow community members, do your best in RP and improve our world bit by bit.
The issue in gaming communities like these are younger lads think respect is power and vice versa, That the way to the top in a community is to grab admin, or developer or whatever. last thing to do is try and become a staff member, it comes natural if you are likeable and reliable. My advice is practice your social skills, personality and actual digital skills, things that will be transferable to real life, by being a good organizer and designer people will come to you.
Bit of tough love, doing a poll and looking for acceptance can look weak you don't need to do this, if i remember i was speaking to you on the jungle server few nights ago and you were talking about making skins, If you are having trouble thinking of an idea, take one of the new vehicles and make a skin for that, not a pink Mrap because jungle life is going for a realistic look. Throw it on discord and dont be afraid of critical feedback, that critical feedback will give you the tools to grow and develop as a person and a designer! don't take my criticism to hard though, your enthusiasm is truly inspiring.
Best of luck and just be you, your a good lad. Don't listen to the haters, they are weak.
