I had planned to state the way I came up with my votes because I always appreciate it when someone takes the time to do so when I'm in the running.
So here it is:

The Tower of Eight Turrets. by Bogie : I like this but the lack of labels I think held me back. Maybe if you hadn't done like tend to do and got moving before the last minute, . The stone layout on the top of the wall should bend with it. Still a great entry for doing it so spur of the moment.
City of Vafildra by dasneviano : VOTED FOR I love the wash/watercolor feel to this.
Circle of Eight - Lower Levels of Anguish by Fury : I think you are going to be really great with textures if you keep this up. My only issue with it is I have a hard time figureing out what I'm looking at. Maybe it's too busy or I'm not getting the depth perspectives right or my eyes are just too old. It does slightly remind me of one of those 3d images you stare at long enough and things pop out at you.
City of Okktor by jbgibson : unfinished but a cool start.
Kumediron by maackey : unfinished? Not sure but I think those are towers...they do sort of look like they might need to be censored
Chamber Room of the 8 Worlds. by timallen : VOTED FOR. I like how clean it is and although simple it has a great rpg game feel to it.
Octonia by waldronate : Almost voted for this but that coastline was just too much for me to accept. I love the interior of the island. If the outer edges would have been a Seawall I would have definately voted for it.

These are just the ways that I used to determine my votes. Much of them are purely my own feelings and opinions which understandable others will not agree with. I merely wanted to let you all know my thoughts and thereby the why or why not of my voting. So often in these challenges one must nitpick or find something they don't like in order to whittle down the votes.

As far as the multiple votes go I think there are a couple of things to mention.

First, the website polling software has real limits. For example, even when we would be limited to 3 votes or whatever there was no way to actually stop someone from voting for more. It was only the honor system that kept things in check.
Second, it seems that even with open voting we have not only a clear winner but a more interesting perspective on how the other entries lined up. For example if we were only given one vote, I can say with good confidence the entry that is currently winning would still be winning. The only difference is that all the others would have zero or very few votes.
Finally, we are not set in stone on how we do the voting so we can change things. I just don't see us spending the time to code up some fancy system...and by "us" I mean RobA
