Aliasing artbirchly_(artist) → birchly
Link to alias
Reason:
This artist signs all their work as simply "birchly"...also their Tumblr is named "birchly" as well. Also I don't see the need for a (artist) suffix in this case at all.
Example of signature on most recent work:
post #1466878
Tumblr: http://birchly.tumblr.com/
Also alias:
artbirchly -> birchly
