I like the lightmap + dynamic lights the most and i don't feel like it's getting too bright. The last scene looks a lot brighter than the lightmap only version though, so i'm not sure if you were aiming for the darker part or the brighter part.

The blury look actually looks more like a bloom effect and nice. For example i really like how the last pic on the 2nd example looks like, it's quite soft and has a really interesting shading.

Just my opinion.

Are those models all from your last scifi pack? I think i really need to get one of those oneday.. just to go crazy with my pro license hehe. Looks really awesome.
