Plus I forgot I like Ghost Ship #1. Riker and Data's heads look funny and thier faces too round. Plus Mister LaForge doesn't look like himself. Maybe they didn't know who was gonna play the characters.
Of course they knew. Those are clearly representations of Spiner, Frakes, and Burton, and the latter two look very much like they did in the early first season. The artist's rendering of Spiner is off, but it's obviously meant to be Spiner. If they hadn't known who was playing the parts, they'd have had no way of even approximating what they'd look like. Especially in the case of Data, who was originally conceived as Asian or Pacific Islander in appearance until Spiner was cast.
Plus is that white space ship supposed to be 1/2 of the Enterprise.
No. It's an upside-down image of the original battlestar Galactica seen from the front and below. It's the second time a Trek cover artist used Galactica imagery; the cover of The Romulan Way has McCoy and Arrhae being strafed by Colonial Vipers.
