I tried to catch the athmosphere of my kids school (locker room of the gym hall)
modelling and rendering in Blender 2.61 (cycles)
rendering time 15 Minutes
how do you like light and composition?
I like it a lot.
Awesomeness!
the shoes make the scene creepy 
good job
Overall I think it’s a job well done . . . except . . . the wood looks too ‘new’ . . . it needs some grunge and wear like the rest of the room . . . and . . . maybe a little more specularity on the metal hardware but some corrosion added to match the other stuff
just the same . . . I like it . . . good job!
