I'm starting to take a liking to Fine Art America, they create prints on demand, framed and ready to hang out of original paintings, for those who want a large artwork but may not want to purchase an original this is a great option, I set up shop here: http://susanna-shap.artistwebsites.com/

Here are some categories
tree paintings

floral paintings

abstract paintings

landscape paintings

cherry blossom paintings

texture paintings

poppies paintings

contemporary paintings

modern paintings
