Most criticism concerning quality up here is completely unfair. Yes, there's a problam, but a purely technical one. Look closely. CoC is showing us 6MP images in 60k files - that's bound to have been encoded at ridiculously low jpeg Q factors, and cannot help but show ugly artifacts at 1:1 magnification. I guess OP is just showing these as samples with intentional high compression to keep sizes down.
As for creative quality - well, I'm not floored but then that's just personal taste! I still respect the initiative, and would be curious about the hinted tutorial.
