How to Design Billboards for a Realistic LEGO City?

[Zephyr261]

Hello!

So, I am starting to create a realistic LEGO City Layout, based off of metropolutan areas like New York City or Hong Kong. I want to have billboards in my city to add the feel of Corporate America and commercialism in my city (which are defining features of cities like NYC). I abhor stickers, because I would rather have a brick-built sign than a sticker (I reserve stickers for things you can't build, like a menu sign within a building). 

Any tips on making realistic brick-built billboards? I see all these cool images online, many of whom use SNOT, but I don't know how they specifically built it. I am quite new to MOC building in general, so I appreciate any and all help! Thanks
