just a hall, nothing awesome
That looks like a place that I could have a really nice time in.
It’s actually rather pleasant to look at for some reason. 
oh i must’ve forgotten: i’m looking for comments %|
You could add some textures…
caustics (photons in yafray)
caustics…what about 'em?
anyone have a tutorial on that? i’ve seen one around here, but that dealy with glass, not reflections, (last time i remember, anyway)
it’d be even cooler if there were more details on the walls… like computer terminals or something. it just looks like a hallway on a spaceship, so some tech stuff would fit in.
i dont think i’m going to add anything to this, but i’m getting ideas for future projects 
Could use more realistic lighting
caustics can be reflected and/or refracted. In case its reflected (as by a mirror or a chrome ball) then set anyway an IOR value in the Ray Transp tab of the Shading (F5) menu. Cast photons as usual and enjoy 
Modron gave a link to IOR for a lot of materials here.
Hope this helps
ok, but how do i do caustics? yafray? yafray wont work for me (error, then crash :< ), so i cant do caustics, the way they did it that tutorial i saw around here anyway…
can it be done with blender internal?
My comments:
-Add textures!
-The shadows of the cubes look blocky.
-The mist at the back starts too abruptly, make it a bit more gradual.
