clean and nice design

ı don't know why but my eyes are looking for a lot more detail. Still these are pretty good in terms of design.

 I the big gray one.  Not too much detail.  Looks like a toy.

Thanks! I'm not sure though about the perspective. They weren't for a vertical shooter but a top down one, so the ship would rotate 360 degrees and go anywhere. If I added perspective wouldn't it look as though they were constantly flying upwards or downwards?

I like those. A bit of a perspective could have helped ;3
