What are the characteristics of renaissance paintings?

Florentine Renaissance architectural characteristics:

• a Hellenistic approach to new structures
• secret passageways and spacious rooms for nobles
• Afresci or frescos considered very high status: on walls or ceiling
• cross shaped cathedrals built

Each of these characteristics can be found in Florentine architecture: some will recognize prominent examples of buildings with these precise points.( For example, the Palazzo Vecchio, Santa Croce, or Santa Maria Novella.)
