I have mixed feelings of these.
The minis look decent and detailed, but resin can be pricer than other plastic (like the stuff used in Bones and the WizKids Deep Cuts; I adore that you don't need to prime or wash the latter).
The Original Series ones look good. Just fine.
My one request would have been swappable heads. Make all the heads separate pieces with common joints, allowing you to pick the head of your choice. So you can use the one set of minis for the Enterprise crew but then put Sulu's head on Kirks' body, Spock's on Bones', and Scotty on Spock's to assemble the new crew of the U.S.S. Jester (or what have you). So the minis double as a fairly generic crew.
Yeoman Rand would have also been nice for a wider range of women.
The Next Generation ones are from a curious mix. You have Season 1 Yar, Season 6-7 Troi and Crusher (that looks more like a S1-2 jumpsuit), and a season 3+ Worf. But then you have Riker, Data, La Forge, and Picard in their unfortunate Generations movie duds. (Shoulders don't look detailed enough for the First Contact onward uniforms). But, adding to the weird era mismash, the badges for everyone but Yar are the Generations ones.
Dammit, pick an era!
