I guess it depends on how much walking space you want. In this current configuration you have quite a lot of space for moving around, but do you want that? I would personally go for an L shape to maximise bench space with one section at a different height for seating. Alternatively, you could just have a standard L shape with seating on one side. Either way it's going to be quite a nicely sized kitchen.

Hi Lil, I believe your original plan works much better than the revised version. While the notion of ideal working widths is great, the larger problem here is the post. I worked on a project very similar to this last year where a post could either be connect to, or separate from the island. What we found was that by separating the island the space between island and post became very awkward. It's not enough of a space to comfortably walk through or be seated at the island in front of. Instead of your room feeling open and generous in proportion, it is going to start to feel cramped and awkward. We have a kitchen in our showroom (Kitchen Studio Tauranga NZ) with a 6ft gap between bench and back wall and it works wonderfully. It allows someone to work at the sink and a second at the island with ease. Stick with the original plan. It will feel a lot more spacious, without compromising work flows.

Hi Karina. Haha very funny re your art piece, KitchenAid! Baking is so much fun; I'm a baker from way way back, and you learn by just jumping in and doing it. About the height of your combined dining/bench table, it's pretty important to have a height that's comfortable for you whilst you work. I'm tall and my family is too, so we had the benchtop height built higher so we are not getting backaches from constantly having to bend over to work. It's really more important for the one who does all or most of the cooking & baking to be comfortable as you can spend long periods of time reading and working out recipes, then putting it all together. Likewise, if you are shorter, choose a table that suits you. Best wishes and keep us posted.

White-matte cabinets (flat panel, not shaker) and white bench (or maybe epoxy sealed marine ply??...siriuskey can tell you about that), mirror splash. Love the ceilings. I personally would go for a modern, stream-line, no handles, integrated appliances look. This space has real potential to be very cool, even with the slate. It doesn't need any more more texture or darkness. This is a nice kitchen, you should be able to sell it on ebay.
