Looking for feedback on this floor plan

We're building on a piece of land with a pretty view from the back of the house, so we want to make the most of it with our floor plan selection. I like this floor plan overall, but I feel like it’s missing a half bath on the main floor.

Also, do the showers in the basement seem small to anyone else?

Any thoughts, suggestions, or advice on improving this plan would be greatly appreciated!

For reference: Donald Gardner plan #1403 D
