I'll apologize for the short comments up front.  Last second trip three timezones away has me mixed up.  I questioned if it was worth it or not but I like trying to comment on each because it makes you look at each one more intently.  Any way, it was a great group of shots this week and congrats to everyone that submitted.
truettray - Love the color and the composition.  I'm unsure if the slight wrinkle in the tablecloth adds to the image or takes away from it.
acearchie - Great idea but it's actually too minimal for me.  I like the idea of the boat in the fog I just need to see a little bit more of the boat.  
imac wannabe - Nice shot. At first I thought Mars wasnt't isolated but then I wiped the dust off my screen and realized how black the rest of the sky is.  Great job on exposure.
Indydenny - Nice composure and I like it in B&W.  I think i'd like to see the top of the tree in the frame to emphasize it more as the subject.  Needs to be a little less going on in the frame for minimilism.
oblomow - That's a take on minimilist that works too.  Cool. My critique is it's just a picture of a room (but a unique take on the theme).  I wonder if you could've filled the frame with the theme while still implying "minimal"?
Parkin Pig - Nice composition and I like the minimilist type sculpture as your subject.  Black and white helps for this weeks contest but the stone wall takes a bit away from the "minimalist" feel.
themumu - The soft colors and gradiation is really nice.  I'm assuming this was taken through an aircraft window so get job on getting a nice image.  Though the horizon looks straight there's something that makes me thing I'm leaning right...probably the clouds.
sim667 - Cool idea and an interesting process to get the image.  I like the framing that the glue gave.  The fly is a little blown out but I imagine that was hard to control.
zObsidian - Unique image.  I guess macro is minimal by nature.  I like how the background makes it seem suspended.  Is it suspended somehow?
Berlepsch - Another good macro shot.  Very nice DOF on the flower.  As a macro it's not quite what I was looking for with minimilism.
pukifloyd - Cool idea for a shot.  Nice job on the DOF, it's hard to tell that it's upside down.
nitromac - Another cool one.  Nice capture and I love the tone of the pic.  Would like to get rid of that tree.
Cyclops62 - Hmmmm, interesting.  I think I'd go with abstract over minimalist for that one.
Jabbot - Nice job on isolating that light and getting the black so black.  The centered composition doesn't really work for me but I'm not sure how else you'd do it.
someoldguy - Nice moody picture.  Just enough of a view in the fog to make it work.
Ish - Nice.  The smoke really makes it and it's quite film noir-ish (is that a word?)
Firedept - Looks like fun.  Not really what I was looking for in the theme.
Charpi - Nice shot.  Black and white really makes this one.
AlexH - Nice landscape and black and white works well for this one as well.  Well done.
NeGrit0 - Like the color.  I'm not sure if it works for minimalism though.
Alexander.Of.Oz - Intersting idea but there is just too much of the bark for me.
gaswerks - Nicely done image.  Nicely composed and I like the sepia.
Illuminated - Love the color and the black.  I like the hands and the lights.
MacRy - Love the colors.  Simply done and yet it's quite sophisticated.
fireman32 - Beautiful night sky.  Good job on the tree line, it's in just the right spot,
Apple fanboy - Still a nice shot.
needfx - Great job on the depth of field and an interesting idea
And the winners....
