My take on this is sometimes I like to use a particular person's freebie a) because I can't make it myself and I need it for a scene or b) because I can't make it myself and I absolutely love it. I try to do most of a scene myself, I can usually do decently about 80% to 95% on my own, but usually need a little something that I can't do myself to help elevate the scene. That said, freebies are a good thing. As long as they aren't the whole thing. But then there are artists who do collage work and that is essentially the same as taking a bunch of freebies and arranging them, so its all art its just a personal taste thing. :)
