Haha, that cheese is the best!
Nice ! I like the cheese in particular It looks like PacMan… Be careful with the glow, the white areas are too white I have to admit.
Btw, there is a problem on the top of the teapot, the defocus makes strange articfacts appear…
In all of those it looks like you modifid the grid. How do I get the scene?
All are very nice, the cheese is my fave. It looks a bit like the slice is hovering though.
Cheese is definatly the best.
The dude in the boat is funny, Great job on the cheese.
Thanks all!
@Pixelvore: thanks, You are right about the glow, and also about the weird top of the Thermosphere, I tried to remove it with photoshop but it didn’t really help much. I see if I can remove any more
@Alienkid10: Thanks, I have not modified the grid. The scene can be downloadet at cgsphere.com
@blenditall: thanks, it is not hovering. I have checked

A little clone tool use could buff those artifacts right out.
I like the cheese, about getting those artifacts out I use an old version of Paint Shop Pro but I’m sure photoshop has clone.
good idea, Il try that
You didn’t modifi the tex? It looks like you did.
Lightning my friend… Ok in the last one with the water, yes I changed the tex to get the sky.
SO HA I knew it!!! Teapot colored lighting?
Yes hehe.
