I adopted my fursona, Lighty, 4 years ago from someone who was giving away their unused characters. That's also why her name isn't that great (full name is Lightning)--she's from THAT era of our art.
I'd feel bad changing her name now though since I've had her so long.
I've tweaked her a couple times but she's got the same basic elements. I think she's still recognizable at least. Mostly just adjusted colours, added some back stripes, and rarely draw the headphones these days.Then: Now:
My FIRST fursona (that I designed!) is still around too. She's maybe 5 years old I guess? Her name's Akiko. She's mostly just had colour adjustments too--her adjustments happened maybe 4 years ago, right before I got Lighty, and she hasn't changed since. [Lighty is my second fursona]Then: Now: (Sorry for long comment. I've probably told you this before lol but I have fun repeating it.)
