Scope of work requires consulting with an architect.

Design style is an overall group of characteristic design elements that are generally accepted to collectively define a particular look (e.g. mid-century modern, French country, etc.) whereas theme is typically used to identify a specific motif (e.g. Disney kids' bedroom, man cave with sports theme, etc.).

As mentioned above create more moodboards, 2ds,3ds or sketches of different store designs say furniture store, Jewelry store, kids store, book store, or may be 1 shop store, etc . Also your basics on color theory ,lighting , flooring and electrical planning should also be good. Whatever design you add in a portfolio it should be backed with due thinking and explaination even if the designs are simple.
