Kremema has been doing digital art since 1997. This is a very cost efficient way to get your hands on a very beautiful painting, wallpaper, or fabric. In addition, you can receive different sizes. "I absolutely love making digital art; its surprisingly easy making paintings appear to be made of acrylics, watercolor etc. The process of printing has many different options. There are multiple different canvases and materials." -Kremena Lefterova
If you do not have the finances to purchase one of the original paintings, buy one of the first couple products of other artists who produce digital art. But, you need a guarantee or certificate of authenticity, so that the piece that you have bought will have un-investment value.
Once you buy one of the paintings, you will obtain the only one. The illustrator, Kremena, only has the original.
