You know, I understand where you're coming from. Artists spend a lot of time alone and/or in their heads. When it comes to any sort of external evaluation or validation, we can't help but stress- it seems inborn into the way many of us work. But this message board is a small fraction of those in total who apply and get in-- and don't. If you really want to learn and improve- there are countless contemporary peers whose work is so readily accessible online as well as thousands of years of visual history. To compare and be compared here seems like a very myopic way of looking at your art and portfolio. It does provide context, but I would say that it's not very constructive.
At the the same time, I think one should resist hounding on another user for website details-- you know, there's a thread explicitly for that and if it hasnt been shared yet it hasnt for a reason. In this age, everything is recorded on the Internet and there's a reason we all have anonymous usernames.
