That was 8 months ago and her last favorite is 6. I even sent a note to her (5 months), which is unread to this day. A quick shout from me on her page (1 month) is unanswered as well.
I'm actually worried that something bad had happened to Euclase and it would be already enough to see some small sign of life from her.
A friend of hers has provided me with the info that Euclase has opened a new account, apparently after forgetting the log-in for her old one: http://www.furaffinity.net/user/sionnachartach/
She has uploaded new art two months ago, but has since become inactive again (PN a week ago unanswered).
So be wary should you plan to commission her.
