Actually, I think 30 dolars is not that bad for a good character model, rigged and animated.
But the quality needs to be good, you will sell for anyone, not exclusive… I think we need some video of this character running… what I can see from this picture, is that it does not worth it, sorry
For sure it’s expensive, i have 2 zombie models with 39 animations + source files + source animations files, 4k poly count with nice zbrush details, at my store you can buy it for U$ 39. So before you put price at your models you should take a look at other models at asset store and compare to your model it will help you decide.
