Well...yes I can't disagree with ANYTHING Prey said.
This is one of those mods that beginning modder always tries with friends, and they all love it because they have never seen anything else. Well guess what? If it toke you under two days to complete, then do not release it
here. The halomods community has been around for a long time, and do you not think that they have never seen this before? You said you got tutorials of this site, so you cannot play stupid for that. Sure, I made a few projectile swaps in my day...I may even release my first mod for kicks and laughs, but not here. Im not sure I'll even post a download for it, I may just put it up in the pictures forum.
So please. Before you release a mod, make sure you have spent enough time on it, and make sure there is something new in it. Otherwise, keep the map to yourself, and learn from it.
EDIT:
Here is the first mod I ever released, or finished for that matter
