With the risk of sounding like a dick, that's not how (video) game development works, and that's not how Telltale went into creating the game.
Since they already had the engine, they only needed a setting, a story, character design and global description of the gameplay. Then, before they began working out the assets, they made sure they fine-tuned everything.
Graphics and animations most of the time comes last
And there's a reason for this. When you dive head-first into developing games, it always turns out shit. I don't know exactly how Telltale did it specifically, but in the software development department, we always go through several stuff first. We always plan out, we first want to know what our software is all about, what it should do, what is important. We prioritize stuff, see what works and what doesn't. During this phase, visual design might also be done.
Then we either prototype, to see if our ideas work, or just go ahead and build the engine. It is mostly preferred to do prototyping, as you can more easily discard ideas in this stage, but as I am not a good programmer, I always skip that phase. It's only after we know stuff works we actually implement the visuals we planned earlier.
It all makes sense even. If you don't do all this, you end up with a product that only barely works. Visually it might even be apalling, as you might end up with different styles. Only through planning you could make something that is at least half-decent. It literally is what separates a bad game from a good game.
The base line here is that developing a game takes planning. A lot of fan and group projects failed because of bad planning.
