When I was purchasing isometric pixel art a few years ago I was paying 3.5k per 8 sprite sheets like the attached example. I was sometimes paying certain artists upto $500 per 180x180px for more detailed game elements like buildings, trees, and etc... The quality of art can make or break a game.
How much is fair price for high quality isometric Vector graphics? A company of a friend of mine was paying around 15k for the graphics for small arcade games a year ago. Their games used 2d vector/vexel art.
I have never paid by the hour. I have always negociated a price for each job based upon the number of pixels and the quality of the work. This below is Copyrighted. Don't take!
