I have not heard about the 3dsky.org It seems to me the business modell there is simillar to photo/vector graphics sites. It works because the price is fixed. CGtrader is a free market though, so your proposed approach here is just undercutting the rest of the vendors. I do not care about low quality assets being underpriced, no one buys them anyway. Your work is top quality, therefore it should be priced accordingly - in comparison with other assets on this market. What works well somewhere else does not guaranty to work here, not when looking at the big picture anyway. Let me know when your bed will have 10 sales here ;)
