As a tip, if you sell exclusively on TurboSquid you are also entitled to sell on partner sites FallingPixel and Exchange3D. Any models in the exclusive SquidGuild can also be opted in to sales at a3d.jp distributing your models to a broad Japanese customer base. Obviously I am conscious of being overly salesy here, but I do think you get a lot of bang for your buck being exclusive. Again, it is still better to be making money selling content than not at all so be sure to try out a number of marketplace sites to see how you get on.
