She's alive and active on Facebook.

Tell her that you know she's active on FB and seems to be ignoring you and question why.

I've heard about her having trouble with commissions and especially with trades in the past, as well as heavily referencing/tracing over things. I never heard if she cleaned up though or not, though this definitely doesn't look good. :c

I'd suggest doing what hellebore said and call her out on ignoring you, maybe if she's active on facebook send her a message there first?

there are at least a couple uploads in her gallery that are really obvious traces (imo).. :/

for example, there's this one, which apparently was a commission: http://www.furaffinity.net/view/2940495

..was the commissioner aware they were paying for traced art?

I know she still owes me half a trade. She never responded to me, and after she asked me for the trade and did my half, she told me she was afraid to draw dragons (my character). I've heard the same from several people though. I think she took on too much and didn't care to finish. I've seen her posting of FA though on people's submissions, so she was at least semi active as of a couple of weeks ago.

I've been friends with her for yeaaarrss (makes me feel old saying that XD) I'll advise her of this and bug her to get ahold of you

FYI: your icon is very pretty

Whoops! Posting from my other account. :B

She owes a good friend of mine a trade half... And also posted a raging journal about how said friend will not likely be getting the art Cicatrizesp owes her.. becuase she's too busy or something.

Lame. I used to like her style/character but now I've lost pretty much all respect because of her 'owed art' attitude.

She tends to take too much on. She approached me about a trade a while back and took a looong time to get me her half, and it felt a little rushed when I got it (I do like it, though). It seems like she takes on a lot at once and gets overwhelmed, I think she's just an art lover that hasn't gotten a good feel for her own limits yet.

That said, it certainly doesn't excuse her bad habits, and she should at least be updating you about things. Ignoring customers is one of the worst things an artist can do, I wish they'd understand that.

Bought a traditional couples icon from her (Or it was a trade..) but I basically had to twist her arm to get her to scan and mail it to me. :\ Not surprised she's here.

Sounds like to me this should be more of a beware than just lost contact, especially given the testimonies in the comments in regards to this artist. You've been patient long enough, hopefully you can get either art or a refund out of her.

i had a friend who had a lot of trouble getting a commission from her a little while back. she basically ignored any comments from her about it and then the product she (finally) got looked really rushed and awful (at least to me). :/ good luck.

Sorry for my delayed response but I've been hesitant to respond to this because I feel like an asshole in the first place. :/
First; yeah, I have had quite a few different health problems. I got diagnosed with fibromyalgia, I may have carpal tunnel, and I have several different dental problems.
Second; I do, as Kayla-la said, have a bad tendency to take too much on; I sell my art for cheap so that people can afford it. It's also the closest thing to income that I have. Hopefully I'm getting a job soon but since where I live has a pop. of less than 12k, it's been pretty rough.
Third; I realize that none of what I've said is any reason to not note you back on FA. I'm truly very sorry. I haven't drawn anything in about 4 months now, not because I haven't wanted to but because it feels like I just can't.
You shouldn't have to suffer for that though. I'll have your art to you within a month.

Again, I'm very sorry. :/
