My portfolio is mainly 3d animation and Illustration (200+ videos, 20 years of expirience in animation), and I can't accept to sell them for 5-10$, sometimes I need week to produce one animation and to see them taking 85% of money, I will simply stop selling there and try something else.
Shuttersock will probably decline without new quality content being added regularly.

I don't upload new content for a while, sales are at such low level that I don't see any point in investing my time with pond5.I will wait few more months to see what will happen with sales and then decide is it worth to keep my videos there.Past two months sales are 
down almost 75%
