This is probably gonna be painstakingly long but I saw a lot of good and interesting points I wanted to add a few cents to (or simply agree with in more words).
I agree that 'workflow' should be the starting point of a design setup. Its often forgotten or neglected in design. And also too often 'cookie-cutter' standard recommendations like 'kitchen triangle' are followed, that aren't necessarily applicable to how everyone cooks. Personally for example I tend to do very little cooking in water, so I frankly don't care much how accessible my sink is in relation to my stove... I don't even care much about the fridge to be honest, since I tend to grab everything at once before cooking. I care far more about where I have my prime prep-space and cutting space compared to the stove. But ask 10 different people waht they use the most in a kitchen and you'll get 10 different answers... whats most important is that the setup conforms to how you cook to make that the most efficient as possible - with the least unnecessary movement.
Personally I hate 180 degree turns though at least for cutting / prepping. Hence why I really prefer a generous amount of cutting / prep space next to the stove. It's far easier to transfer stuff just a meter to the left without dropping anything than to do that during a 180 turn. Your mileage may vary if you're less clumsy but it's worthy of consideration.
I agree that I'd probably move the stove a bit to the left. The small part to the right of it right now looks a bit... like a dark forgotten corner that's too small to be useful, doesn't get good lightning, and its a bit... iduno.. weird. Like a 1 meter gap without a cupboard. I think it would look better if you at least filled up that gap with open-shelving, and-or just moved the stove a meter or so to the left, and then that whole space to the right of the stove becomes far more useful.
Also, lightning. Could be because of the rendering but that really looks like a 'dark' corner. My major complaint in my own kitchen is that in some places the lightnign isn't that good, or for example I try to rely on ceiling light but in some positions my own body ends up blocking it. Lightning can really make or break a kitchen, both aesthethically and functionally.
When it comes to that large open wall I can see both sides of it. Filling it all up with cupboards adds functionality but will make the whole place feel more cramped. A compromise solution is to add at least some open shelving for stuff that doesn't look like crap. Plates, glasses, pans, whatever. Open shelving adds storage without making the room feel smaller.
Unless your ventilation is really superduper awesome though it's preferable if anything on open shelving is stuff you use at least on a regular basis. Personally I really like having all my pans on open shelving because it's really convenient when cooking, but others may consider this a complete nightmare because it looks more cluttered.
As a compromise to a compromise you could also do it on part of the wall, like the part to the right of the stove.
McMan also makes another very good point about this: only having low-height storage means you're constantly bending over all the time. As a tall person I can sympathise with this; all my most regularly used items are all stored above the waist level. Anything below waist height is - to me - subpar unergonomical storage.
Yeah trash is important to consider.
Unless you're someone who's a big fan of using garbage bowls while prepping, I think it's as important as anything else in the 'kitchen triangle'. When I'm prepping I go to my garbage more than to my sink. Since I'm poor and live in a rental kitchen for me the easiest solution is to just have a standalone trash can that I can move around, so I literlaly just slide it over next to my prep spot, but there's a million other ways to go about this (and most are far more elegant and prettier than mine). Bottom line is just to keep it in mind when planning. It bothers the hell out of me whenever I'm at my parents place that they don't have this set up efficiently.
Those kitchen all tend to share a similar '0 clutter' aesthethic. If that's what you want some things to consider:
-Figure out a solution for any appliances you have. Consider making dedicated 'appliance garage' cupboards that you can close off with a door or something.
-As mentioned by others such photos are often made in kitchens that see little actual usage, and / or
after someone cleaned up all the clutter for an hour.
-A lot of this is about discipline to actually put everything away in cupboards all the time so it's not cluttering up the islands / counters. A large factor in this is to make sure you have enough storage space and it's convenient enough that you'll actually bother to put things away.
