Artist requests to use shalon instead of this.
From the FA journal:

I've noticed some of my stuff being added to e621 and honestly go ahead I'm more than fine with it if it's just my characters (if with another best getting their permission too). Although I will ask that people use the artist tag 'shalon' instead of 'shalewd' since both of them are my aliases, though having it under one roof might keep it less confusing.
