The first room is just too busy with too many things, colors and patterns. It makes me anxious....I think I'd take everything out (except maybe the green lamp and chair)and start over.
The second one is ok, it looks modern. I'd get a different floral arrangement (bonzai tree?) and maybe a larger lamp and a rug to bring in some warmth and pattern.
The 3rd room is nice although like @Oznell said there are too many little nicknacks on the sofa table. I like fewer more substantial things....it's more calming and attractive. The lamps aren't my favorites, I'd change those up.
Also, I think floor to ceiling drapes would be nice here.
@LTT1 Fun post!
