That is consistent.
From my point of view, rightly so. Try placing the furniture to scale as a test. Always going through the dressing room from the home office to the toilet would be annoying.
Very pragmatic. What does your heart say?
The staircase situation is, as already wrote, something to reconsider.
[*]Place the access to the 2nd study through the first one, then the rooms will be more practical.
[*]Make sure you have access to the bathroom upstairs from the hallway. (see above)
[*]Go through the furnishing and your routes, does that fit your lifestyle?
[*]The pantry is currently very modern but in this format questionable from my point of view – only a few shelves are possible. Optimized routes would be an access from the hallway, saving a lot of walking after shopping.
[*]The captain’s element is not functionally necessary; if you love it, keep it – I find it somewhat contrived.
[*]Do you have to build square? If not, you can get a better room layout (and less hallway space) – unless you are exactly into this ephemeral trend.
[*]The windows could be somewhat larger, especially in the living room on the ground floor.
[*]Have you paid attention to what you look out at from the windows, what kind of light you will get...?
[*]The side entrance is a great idea if you have a room behind it that you can use as a "mudroom" – for example for a dog – or is the Corvette getting a garage? The big gasoline engines smell quite a bit, I wouldn’t want that inside the house.
For the budget, I would build something a bit more inspired. The design seems very conservative to me within what "people do nowadays" – like a Mercedes C-Class sedan. Every person is different, maybe that’s exactly what you want.
