What is the trend lately? Are people buying more abstract, impressionism, realism? Or are they just buying something that matches their decor?
People,as I talk about the majority.Always tend to bend with the trend.Whatever invades the market,is diamond to their eyes.They want to go with the flow and make themselves seem like highly trendy personalities.They will buy anything which their neighbors do,in burning jealousy.Look for what is popular an you will know what 50% of the population prefer.And some people are show-offic,they will go for anything which is shiny to the normal eyes and could be shown off,thus they buy whatever smothers their pocket.Other people are real admirers of art,they are highly knowledgeable and intellectual people who understand the beauty of art,who flow with the brush strokes and who melt themselves into the life of the painting.So,it depends on what type of mentality a person possesses.Thus,they buy whatever matches their decor.
And yes,art is of many types and classes.Novels and books are a class apart,painting and drawings are a class apart.When you mention 'Artwork',you should also,mention the 'class' of the 'Artwork'.That,will avoid confusion.
stories that are catchy to the eye, something that demands the readers attention when they pick the book uo, like the Magical spells book. Everyone loves to think they could put someone i=under a spell!
I personally like surreal art but it really does very from person to person
depends on what your art is about and if it can or will sell!
