The Knifecycle website is now in closed beta. I have used a variety of images from my favorites for the site, giving full credit and a link to the artist's DA account (Knifecycle -> About -> Website). If you see your image there and don't want it used, please let me know. I will gladly remove it.
I am building a website for a novel. If you see one of your pictures there (http://knifecycle.com/), please indicate whether you are happy for me to use it. I provide accreditation and a link to your page (http://knifecycle.com/about/#/artists/).
