I wasn't sure, if I had to add a link to the cc-by license, though.

The only thing you have to do, when using CC-by artwork is providing the name of the artist - For me linking to my Steemit profile like you did would be very fine - else to my Diaspora-profile or the website.

David Revoy has written a fine piece about it.

That's a very good link :-)
