I think the weapon effects are getting better, judging by the rather large beam in the screenshot. Not sure what the deal is with that flare right above the beam though. Didn't notice the shield until someone pointed it out, either.
The capital ship (that's being fired on) probably hadn't gone through any changes since the last screenshot (at least, not to my knowledge), but it's good as is. Can't make out any of the other ships.
Judgeing by the orientation (of ships in all the shots so far), I must sadly conclude that the ships reorientate themselves.
The background is, as always, exceptional.
Lighting is still poor though; I would like to see a large lens flare effect or similar when looking into that sun. Not sure why but the light on the capital ships seem reversed. The capital ship infront seems to be illuminated on the side that is not facing the sun.
You guys still got some work to do.
PS. I also think the planets look a little flat, but those are hard to create in and of themselves.
