I'm looking for someone to help us establish what YouToplius looks like as a whole, that way it'll be easier for me, Icy and Co. to get an idea about what we can do from a visual standpoint.

There's several locations that will be mainstays: TGF's House, The Studio, Downtown YouToplius, YouToplius Park, Icy's Apartment, The Rundowns, and Central Avenue.

Here's a basic rundown of what I have in mind, if you're still interested:

TGF's House:
I can imagine his home being a simple Two-Story House with a built-in basement. Nothing fancy, just a simple suburban house on the outside. As for the inside...
On the 1st floor - there's the living room, kitchen, storage closet and garage.
On the second floor - there's TGF's bedroom, Daisy's Bedroom, Bathroom and Game Room.
In the basement, that's where TGF's lab is - just a dim room that's filled with chemicals, past inventions, several monitors connected to a PC, a workbench and the house's plumbing.

Icy's Apartment:
She lives in an apartment building that's being rented out by TGF & Co. Studios.
As for the apartment itself: It's a small, one bedroom apartment with a living room, kitchen, bathroom, closet and - you guessed it - bedroom.

The Studio:
Similar to TGF's house, I can imagine the Studio being a Two-Story Office Building with a built-in Basement - but a lot bigger to compensate.
On the 1st floor - there's the Lobby, Staff Meeting Room, Green Room, Recording Booth, Mix Room, Changing Room, Restrooms and The Storage Room.
On The 2nd floor - there's TGF's Office, Break Room, Editors' Room, Artists' Room (Separated into different "Studios" for each respective artist), Composers' Room, Storage Closet, and Balcony.
In the basement - there's the Electrical Room, The Water Room, and TGF's Studio Lab.

Downtown YouToplius:
To be blunt as humanly possible, I just imagine it looking like a futuristic city in almost every way.
A mixture of regular buildings and odd standouts, references / cameos of other creators (and creations) everywhere, walk-in tunnels with moving platforms that'll take you to different sections of YouToplius, a regular subway, highways, and so on.

Central Avenue:
This is where most of TGF & Co.'s go-to places are: The Ice Cream Parlor, The Café, The Copper Sign, The Tool Shop, The Retro Game Shop, etc. It's essentially the Average Layer's Shopping District, to put it simply.

YouToplius Park:
It's just a nice, natural area that's surrounded by the big city.
A picnic area, a hiking trail through a forest and waterfall, a playground, a reserved golf course, and so on.

The Rundowns:
It's hidden deep underground, right underneath the Average Layer: Most people have abandoned it and went home, never setting foot on the island again. However, for those who are resistant and crazy enough to stay, it's a rundown city that's barely lit up by blue flames in lanterns. It's clear that this area is the most crime-ridden area in all of YouToplius - with chalk outlines, broken windows, and stains everywhere.
