I highlighted a few of the main issues in your "level" but there's multiple other ones I didn't bother to highlight and not only will there probably be more problems if I looked further, but there's a lot of things that make the level sort of ugly.
It's clear you used a random ios app you have no experience in on your free time to design a village. That level, while you may feel proud of it, isn't good enough to be released in an MMORPG with thousands of players, let alone any decent game. On top of all the problems i mentioned earlier, it's an extremely boring level. There's nothing interesting about it that would make you want to explore, and it's an extremely bland generic village.
As far as I remember, you lied about having a 10k-100 spar record or something so no offense I can't take your word for it on "45 minutes." I've done levels with tons of various softwares, and never have I designed anything even close to that timeframe. Even a basic RPGMAKER level takes an hour or two (provided I'm actually making it look nice.)
With this in mind, factor in how outdated the levels editor is. Pics1 is a jumbled mess. Unlike most other levelling tools for other games, there's been no update to the one the devs use.
It's clear you don't have any info on this topic, so I don't know why you're talking like you do. If the dev team put out the level you made as a "new town", they'd get raided for a "lack of effort."
Not only that, you have to remember that there needs to be stuff done in the levels. Once the staff have actually built the cliffs, trees etc; using the terribly formatted tools, they still have to add in all the NPCs, shops, quests, baddies etc; that make the level unique from the others.
Like crono said, you should open up the editor, and try to design something as good as MoD town in "2 hours." If you watch any tutorials on youtube, that factors into the time because according to you, you can legit just get a level put out in 2 hours, starting from when you open your laptop. I guarantee you, you'll fail to put out a decent level in 2 hours.
And as for what you said about changing the tileset, that's also not as easy as it sounds. You can't just wish for a new tileset and get one. And if I'm not mistaken, I'm pretty sure if you suddenly switched the tileset, the rest of the world would get messed up.
