/3/ - 3DCG

After comparison whats some very spefific way one can do to know if your model,animation,rigs, designs basically, are up to a standard quality yer looking ante up againsts like maybe knowing in specific what to add or whats missing and the exact value of those additions or just matching up qualities using market datas, or direct computation methods?
Just to be completely sure

What are the aspect of a 3d design that adds up to how many people will be buying it, as in the download/view/sales number? Like a 5$ hand model getting maybe 1000 downloads... how do you measure up the value of this model to expect a good amount of traffic etc.

Oh wait i guess you probably only know ctrl+D and how to pan the camera and usually just copy fanarts lousily and presses the sphere icon 1000 times and calls it hardwork that you cant be bothered to think yourself so dont sweat the big numbers too much and let the real designers answer this thread
