Certain styles are untouched, yet perfect and elegant like an age-old wine. Of course, wine gets better with age, and so does Modern Style!
Strict with rules and stringent with art! Executing what is told and practiced for years is what defines the Modern style.
Not to forget, maligning this style with anything new and trendy is forever deemed to be wrong! So beware you need to be ruly and civilized here. There is no other rule if you need to master the art of “Modern Style!”
