No bother, it's a quiet time of the year in the showroom; we haven't posted our January offer yet so chatting on boards like this keeps me busy. :)
The fridge placement is optimal imo; it's the same general layout that I would design for a room shape such as this; sink under the window (because that's where sinks go!), oven in the centre of the run, and tall appliances at the end of the run.
There's a principle called the working triangle for kitchen design; it incorporates the sink, cooker and fridge in a triangle with enough distance (but not too much!) between them to allow the kitchen to be both functional and aesthetically pleasing.
In terms of appliance placement, I don't think there's much of an improvement that can be made aside from perhaps integrating the dishwasher to make the aesthetic a little better; it's a shame to be walking into a tall panel when entering the room, but that's unavoidable with the room shape that you have.
The dining table looks rather close to the larders; (visually, I'd say ~600mm) .. I'm not sure if that's an accurate rendition of a table that you own / are planning to buy, or if it's just decoration added by the designer, but the general guideline is to have an 800mm gap between "pinch points" to prevent the kitchen feeling cramped.
That's a lot of pan drawer units though (3 x 800mm, I'd guess?), and your cutlery tray is on the opposite side of the room as the sink.
The latter could easily be resolved (swap the cutlery drawer unit to the one left of your oven) .. it looks like a 2-pan drawer unit with an internal cutlery drawer so aesthetically would be identical to the standard 2-pan drawer unit on the right of the oven and would maintain the symmetric look.
You'd then be able to do away with the "extra" drawer unit near the fridge/freezer and change it to a standard base unit in the same size as your sink unit (again, symmetry of door sizes).
This is where integrating the dishwasher would also help visually; the two sides of your kitchen would "balance" .. each would have 600mm dishwasher/unit, 800mm sink unit/base unit and 500mm door on the corner units.
I suppose it depends on how many drawers you feel you need; they're one of the most expensive units in the kitchen (drawer mechanisms are costly) so I try and keep them to a minimum just from the cost perspective.
