Digital art is being appreciated and valued more and more, as you probably are aware. Your abstract works have great colors (I see that you have submitted three). The detail and compositions are strong too. I think the universal subject matter also will appeal to some buyers. Also, the size of these works is wonderful and makes them more salable.

Of course, if you are an unknown artist, it is harder to sell work. There is just a lot of competition and so it can feel like an uphill battle or that your work is being undervalued.The low end of my estimate reflects this unfortunate reality. I am not sure where you are at in your career, but if you can show work in galleries/cafes/competitions and build a portfolio that increases value.

Compared with sales of similar works, the Fair Market Value of this piece is between $200 and $600.
