Please try to provide criticism to everybody, there's always room for improvement on each image. (and I'd like to ask the judge to not make any statements about which one he might pick, but unixfr3ak has been great about that so far.) Just try to keep things polite and on-topic.
Here's some comments I have about each and every picture up so far:
Gorlocks - Has a nice mood, but seems to have no lights in it, other than the photoshopped beam. Also seems rather plain, I would download Cosmic Prophet's sci-fi packs and use them to spruce up your levels. Here:

Con - I have similar problems with this as with Gorlocks. Try adding some lights and getting some non-stock entities, such as those in the link above. I guarantee that if you do that, your screens will look fantastic.
Charging Bull8 - Same really.
Bloody James - Yours gives me a nice atmospheric feeling, but I do have some problems with it. First of all, why is a random chair in the hallway? A hallway, even a hardly used maintenance hallway would hardly have that much crammed into it. Halls are generally kept clear to make walking easier. Also, why is the only light in the hall that's working behind you? There should at least be one further down the hall. Your scene is great, it just needs a little more logic when placing the entities.
SekoIdiootti - I can honestly say that I can't see much from the photoshop effects. However, what I can see looks great! It really goes with a horror-scifi theme.
Bugsy - You don't suck at sci-fi. Just don't over-do it on the bloom/blur next time, ok? lol
dxdragon86 - I can see inspiration from Wolf, haha. Anyways, yours is great, but I would do a few things to make it look better. First of all, I'd change the lights to less of a blue and more of a blue-ish gray. Next, I'd lower the ambiance and increase the light radius. Other than that, you have great placement and design!
PW - Yours is really good. The hallway has great proportions for a space vessel, and lighting is just right. Entity placement is good, clearly defining were you're supposed to walk, and where you're not (aka, where you jump and crouch on to get out of the map, lol). The biggest criticism I have is to add another light on the right side further down.
Gamer X - Get some non-stock segments and some new entities and you should be good to go for the next one!
Warleader - I liked your first shot alot better. In this new one, it looks like there's a dust storm happening underground. Also, all the walkways are black (no lights) but the cave walls aren't. It just ruins the image, which is a shame because it was really good.
TerrorNation - Yours is extremely empty. It seems as though you're in a room and not a corridor, so I would expect more entities around the room. Also, why are there chairs on the floor but no desks or tables (unless they are out of view) I would also drop the ambiance, increase the light range, and raise both the light and its entity.
Doomster - I actually don't have much to say, other than its great! It looks alot like an older sci-fi building (as in, built in our future, but their past. Am I not making any sense?)
RelMayer - I like your screen, but I would change the yellow lights to more of a yellow-white color and increase their range a tad.
I hope this helps you guys improve for the next competition, let's hope the winner picks a good theme! Remember, I'm not the judge but I am just offering cunstructive crit.
