Agree, it could be improved.
I've got fridge / freezer next to ovens .... it's not ideal but not the biggest problem. Your design just looks clunky there because it's a big free-standing fridge/freezer. It would look much sleeker with integrated FF (although that may not be your taste admittedly).
That corner next to oven is going to become dead space. If you leave the layout as is, then you might be better with a wall cupboard which comes down to worktop level, and use it to store toaster / etc. In my equivalent corner, I've got a glass wall cupboard, with lights in it. Which brightens the area.
My parents have got their microwave in the same place as on your plan, and it does look "off-centre". I've got 1 1/2 ovens plus microwave in a tower. Microwave is slight lower than yours, I tend to use the 1/2 oven (other than Christmas Day!!), but full oven is probably only same height as if it were under-worktop.
Wall cupboards are a personal taste versus trend issue at the moment ..... definite trend for fewer wall cupboards, but depends if that leaves you with enough storage and / or if you like things being on display.
Do you have space for a table on the blank wall? Or do you need to factor in seating anywhere?
