I feel like your study needs more furniture. It just seems incomplete to me. I'd try adding another armchair and maybe to a teaset to send the message that guests are always welcome to seek your wisdom.
add some flowers/plants and items that you can hang on the wall, and I suggest you remove the teddy bear from the bathroom and add something else instead
I suggest you look at Diana's house interior for inspiration!
I feel like both have a ton of potential but need more furniture to really pull them together C:the study however seems "too bright?" i personally like really dark study areas with dark woods
The teddy bear in the bathroom is definitely a contrast. Adding plants or other bathroom necessities (shower and box of tissues are good examples) to the bathroom will definitely make it stand out. The office/study will need a better flooring/wall too. The current one (common, I think?) doesn't make it look much like an office. And the coat hanger could be put by the door.
Use the library wallpaper in the study room, also the cool globe, pop up book, display the 4 leaf clover (which appears as a book with the clover in it), typewriter, desk lamp, maybe the letter set. It has a lot of potential. I suggest looking at Beardo's house for inspiration. I don't think the mermaid set would be good in the bathroom. Theres a few more toilets and bathtub items too you could use.
You could try the Tartan rug for the study. Add a cool globe and a fireplace and more large bookshelves.
I don't have ideas for the bathroom though but I hope this^ helps for your office. ^.^
They're off to a good start, but a bit barren overall. I would suggest refurbishing bathtubs for your bathroom and adding items such as an air conditioner and a humidifier in your office. Maybe you could also use an office wall and flooring for your office?

Hmm how about classroom floor or sleep carpet for the study/office? I like the furniture you have already.
Bathroom looks good.. I have bathroom in one of my side characters house and I have shower stall & stripe sink (I think that's the name? From stripe set). Also Gracie lamp & Gemini closet.. cuz they are blue xD
