Thanks to everyone who commented.
The real trick here is coming up with enough of a variety of hull designs so that they are destinguishable on the minis. Thats the mistake I made with the first gron, some of the ships are harder to distinguish than I like. As for the detail, I really wanted to take the time on this. There are some realy nice looking sets out there and I no longer feel that my first three measure up anymore. Those three were done with Truespace 4, a nice prog and all but limited in some ways (that and it kinda blew up on me and never worked again). These current ones are being done on Lightwave 7.0 Final, which is a more powerful tool. It's taken me nearly a year to learn to use it well enough to do these.
