Superb: I admit |'m only a raw novice at TC, so I certainly wouldn't quibble about light-levels etc.
Rather, If I were to wanting a new kitchen of similar standard I'd now know whom to ask!
Speaking from the householder's perspective, if as I assume this is based on accurate drawings of the real kitchen to discuss the proposals, it's a huge step on from the usual brochure photos of possibly the chosen appliances and fittings but in architecturally very different settings. If I were the customer I would consequently have considerably more confidence in your ability to give me the kitchen I want, in both standard and style.
Incidentally, there is something of a precursor to this approach in the 19C, in producing specially-tinted drawings of major engineering projects like bridges, I think similarly used in the contract negotiations, albeit with railway companies and harbour boards rather than private home-owners.
