You know, from early on there was an artist called Arturo Juarez that basically had the exact same drawing style, albeit with cruder quality, so when I started seeing some improvements (and by improvement, I mean less grainy and shinier... ironically, there really isn't THAT much difference in the quality of the pictures. The account isn't there on VCL anymore (I assume its an art purge combined with trying to recreate themselves in the fandom). I had a suspicion that Arturo and Jessica may just as well be one and the same.
Oh and for those who care, I still have some original Arturo pics on my computer. There's no date or signature on them, so it's hard for me to guess when they were drawn. I did, however, download all of them from 2002 and 2003 (when I first started downloading furry pics off the internet), so I'd have to say that He/she didn't quite make as revolutionary a leap in style and quality as they'd like to think.
