I hope you didn't take what I said as criticism, especially when there isn't much to criticize as of now. I just listed specific details I like about K's work, and hope you mirror them to the extent that you can. Not necessarily exactly the same; your preview image you posted was well done, but the focus was pretty different than K would usually do. I compared it to similar scenes in K's original release, and despite the differences in emphasis and focus, your preview image had solid attention to technical details and conveys what you think is important.
Of course it would be difficult to emulate K's voice exactly. I think it would be difficult for most to do that. I did point out it would be noticeable to anyone looking--but as far as expectations, I just hope for a similar level of attention to detail, and following the broad strokes of the outline and level of quality. Unless you're literally ghostwriting for someone, I'd expect any writer to imbue their work with their own style. Again, hopefully you don't take expectations as critique, especially since as you said you haven't released even a demo yet.
Obviously what you've shown us so far is very high quality work, and I think most of us here appreciate you picking this up and seeing it through at the level of fidelity we've seen already.
