3 sigs c/c please...

Not really feeling these tags work on your colors more and if you have trouble with the text leave it out.

There are too many things distracting your subject, consider the depth of field next time when you're working on your tags. :D
The subject and the text just got lost in distracting C4Ds this way. The colors kinda disagree with each other, seems like on places where something should be lit up in blue, it's actually lit with red and vice versa, so another thing to consider. Also the lighting kinda confuses me on this second piece, since the light is coming from the window only and your renders also are only lit up by that, it's not neccessary to place lighting inside the cave, unless you were aiming for something in particular (but that's just my opinion anyway, I was just confused on this one). Nice try anyway.
Let's hope I helped a little. :)
