Looks good, but I think you could make it more interesting by tweaking the tones you’re using - grey letters in a grey environment aren’t really the most inspiring combination. Try creating a better contrast - it will help make the reflection on the floor stand out more as well.
I agree with Paul, the coloring could use a punch up. Perhaps some mild reflection on the walls in the back. Also, you should tweak the motion of the “elevator”. It comes to a somewhat abrupt stop at the end… needs to be “rounded off” with a bezier interpolation IPO curve.
Pretty cool, as is, tho! Like the AO!
i think it would be cool if the text would be like some kinda colored glass.
