I like how they have that 1960's Sci-Fi feel to them. I wanted them to have distinguishing uniforms that identified their jobs (Troopers, Scientists, or Leaders) but still have a unifying element. So they all got the yellow trim, with the Leaders being blue, the Troopers red, and the science team are all in green.
If you're looking some Grey aliens to take part in your off-world adventures or to land in some field and steal cattle, then I highly recommend these figures.
Also, on a personal note. I'm really saddened by all the loss of the recent terrorist attacks. To all my Russian and French internet friends I hope you and all your families are safe and were spared from these tragic events.
