Ok then
First round-Madwak
Mad-I dont really like the style, especially when you only use one color like that. I think there is a way you can better tie the letters to gether to make the style look better, but the way you did it was so-so
Neo-Too cramped for the letters, and am I the only one that thinks the faces should be anatomicly correct when you try to draw them correct? So if anything it takes away from the piece because what should have been cool is so-so when you draw the face weird.
Second round-Neo.
Mad- I definatly like the style, but I think there are some other things you could have added to it, maybe a background or something to make it more then just the block sitting there. More color too. Otherwise I liked it. What I might try is doing some kind of piece like that, but leaving the color inside white, and doing another really light piece on the inside running up and down or something like that. I'v seen it done before in BB and it looked pretty good.
Neo-Good job overall, I like the use of colors and effects better then madwaks piece, which is why you got the vote.
Final round-Madwak
Mad-I like the style, although doing it 2 rounds in a row is kind of repetative. Its a good thing you got the style down then

Again, try to add something more like a background to it.
Neo- Im not sure what happened ehre, but it a step backwards. The letter forms are really weird, and the knot thing in the middle doesnt seem to go with the rest of the piece. Overall it just look bad because it doesnt flow, as well as the colors being drab. The little thing in the lower left is cool though
Overall, the goes to madwak.
Something to think about
: Every piece doesnt need 3D, but what it needs is something to fill the eye when you look at it. The eye is naturally attracted to look at white or empty spots, so if your peice has one huge white spot out of the entire thing right in the middle, the person looking at it is going to look more towards that. To prevent that, you can do things like 3D or glow, or add a background. That why I bet you if you look at a huge ass piece on a wall, it rarly has a blank spot where you can see bare wall right in the middle of the piece. It gives the eye something to look at all over the entire thing, and makes it look better. The same thing also happens when you add color contrast to it.
