Judging by the action shot of the saucer, it looks like (can't believe I am going to say this) it doesn't have enough deflectors? Of course, I have no idea what kind of HP did you give to the outer sections.
I originally had a lot more deflectors on here, 4 each on those blocks instead of one. However, that would make it basically impossible to kill once you blast off all but those last few sections. I could add more deflectors, but there's not another great spot to put them. I suppose I could put some on the end of those section 16s that hold the demeters. The other thing to note is that I changed the color on the deflectors to be a darker green.
Generally, I like the shape and use of sections. However, IMHO the colour scheme doesn't really give the ship's complexity any justice. The colours really dull the detailing that you did on the ships, especially the saucer for it to be fully appreciated.
I'm kind of torn on this. I wanted to make the ships kind of dark and I like how the colors look in general. However, I can see how that kind of obscures the details. I don't know, maybe I'll lighten it up a little, but probably not too much. It's also a big pain to recolor that whole ship, and I'm not sure I want to do that.
I think the colour scheme works quite well, but if I may suggest, a lighter-coloured outline partway through the hull would bring out some of the construction features.
Eh, I'm not a big fan of that effect. I wanted to avoid using outlining if I could for these ships. I want them to look kind of organic and flowing, and the outlining kind of ruins that.
