Sci-fi Faniverse

Samus' head looks a little too big when you look at it for too long, although it doesn't really take away from the picture being epic xD

The Rifle the ghost is holding looks like it was pulled really far back, but maybe that's just me.

I'm not trying to be picky, but I thought this might help you in the future.

Overall, the picture is great, the colouring is amazing... (O.O) positioning is great... just overall really good <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)"/>

Well, the computer is complaining that this critique is too short, so I guess I have to add this... Exactly100

This captures each characters resolve and strength. It also makes the characters readily recognizable as who they are and what they are. Like everything in the world, there is always room for improvement. As mentioned by others before me, the characters indivdual expressions (Chief excluded) could use a bit more emotion. Also, a glimpse at what they are fighting may be in order. A mix of Covenant, Zerg, Space Pirates, and any Mass Effect enemy would give the Heroes A true foe, and help convey the emotion that is on the characters faces.

Overall though, this is an excellent work of art.

This is really well done. Each character has their own personality just as they are all from different games. What's better I like how each one doesn't really acknowledge the others (except for Cortana and chief, but they are from the same universe) it keeps the fact that they are all together a little more manageable in my opinion.

The natural progression of the eye is also done very well. Being pulled up the hill towards chief, but then pushed back down to go through everything again by the light at the top, very well done.

I usually don't like mash-ups, but this one is exceptional keep up the great work.

First off, who doesn't like a good character mashup, rock on there.
I'll jump right into the juicy "what could be better" points, because that's what really matters right?
The faces, like someone else pointed out are a bit lacking. The anatomy is pretty good in most places, but for such a high action piece I think they could use more contrast in order to hold some attention.
The asaris face in particular is quite muted, some harsher shadows or sharper highlights would do her good. Her mouth expression isn't quite convincing, though I do understand what you're trying for.
Same goes for Samus, more highlight. The ghost is doing ok and Cortanas face is spot on.
Other smaller points. Samus' torso looks a bit short. The center and right side of the rocks might use more definition. And the Chiefs armor looks a bit immobile in it's angularity and blockyness, blame the curvy ladies.

Overall great work though, much beyond the scope of work I usually shoot for.

great team 

Epic!

awesome work man! The Starcraft Ghost's name (assuming you are using the iconic ghost) is Nova btw

master cheif getting all the ladies. you awesome dog you

It looks a bit like Master Chief is clutching Cortana's(Virtual/nonexistent) hair, and the gesture seems somewhat sensual...
my biggest confusion is... MC is not a girl. but all the other characters are... was this intentional?

This is truly epic.... Words cannot describe just how awesome this concept is

I would of liked to see your style of Liara instead of photo plating it.
