Constructive Criticism time:
First panel: Bubble looks like its talking to the craft above.
I did get that there was one alien and one robot here, mainly because of the speech bubbles. You may want to back this up with a closer up shot of these main characters.
Second Panel: I also thought the ship might be about to crash here.
Page three, panel three. "How you doing?" looks like he's talking to the guy behind him. Easily fixed by changing it to "How you doing, Globis?"
Upon re reading it to check these bits, I think the story could do with some more room to establish what is going on in this Cloud archive base, in terms of the slaughter that has just occurred. It's all squashed into the top right corner of page two. This isn't a problem, as it makes sense, but if you are going to expand it, this would be a juicy bit to expand.
Same goes for the final panel, If you are going to expand the page-count, maybe a bit more room could go into establishing what is going on down on Earth. This might be as simple as having some recognisable continental masses visible through the atmospheric death.
Most of these points have been mentioned before, but it might help to have another opinion. Don't forget that my opinion might all be balls.
