Guild Wars Skill Icon Artists

I've always been impressed with the skill artwork, but even after extensive searching (googling all the artists from the credits and other misc. google-fu) I can't figure out who the actual artists were.

Can anyone help me out?

Many of the skill icons have been in use since beta, meaning seven or more years ago. I would assume they were a joint effort by many people on the art team and as many artists have come and gone over the years it may be almost impossible to track down each icon's artist.

Also, I will now be using "google-fu" in my day-to-day speech....

Since you are impressed with skill artwork, you have probably already seen this, but it's worth posting again:
