The artist, the genre, the style, the medium, are all secondary in importance to your individuality and your style. You know what you like. Trust your judgment. But in addition, there are a few other things you want to keep in mind that may help you select artwork for your home. Be aware of the space you are working with.
Large paintings can overwhelm small rooms.
Conversely, small art can get lost in rooms that are considerably spacious or cluttered with other home accessories. This not only helps in the selection process, but also assures appropriate sizing for your decorating needs. Think about the type of room you're decorating, and pick the subject or theme of the artwork accordingly. For example, you might consider hanging sports art in a game room. Sunny breakfast nooks look great with bright florals.
