my humble opinion is that the ones on the left have a tad too much glare (reflection) and it gives the models a bit of a pLastic feel. The ones on the right have no glare (reflection) and for some reason make me think of a rubber type texture. So, I'd say the model needs the glare (reflection) but perhaps not as strong as the current left samples.
Aside from that, these ships look great.
Cheers!
