Similar Project (but thats OK!)

Whilst browsing I came across a curious video on YouTube. It turns out someone has 'somewhat' done what I aim to achieve, by 'somewhat' I mean the idea is the same but not the scope.

While this is undoubtedly impressive; the project is confined to just this diner and is unplayable. Whereas mine is a whole section of gameply upto around this point.
Exploring the creators ArtStation link, he explains, this is indeed restricted to just this scene and the aim was to purely create the best looking environment possible using professional-grade industry tools.

Due to time constaints I don't think I would be able to achieve this level of visual fidelity, espeically considering I have a much larger area to focus on. I will though be aiming to create better visuals than the original!
