Thank you and I removed them myself since they were in breach of copyright laws. Initially I put them up since I was browsing websites like society6 and redbubble etc. and “everyone” is selling fan art so I thought what the heck. But then I spent some time looking into matters (good recent feature here for example) and decided it’s better not to tread that gray line.
Now I just tell everyone who asks that it’s fine by me to go and download the fullsize versions of my fan art images (either click on them in my blog here on tumblr or use the download button on deviantArt) and print them out yourselves as long as it’s for personal use only. Most at-home printers these days do a really good job if you get some nice paper and crank the settings to highest quality options. Or you can always use professional printing services. :)
