I didn't mind the shot of Voyager on the Full Circle cover, but to repeat the idea on the next book feels uninspired. This is made worse by the feeling that the artwork is unfinished and could use some polishing.
My issue with these is that, with the notable exception of The Never-Ending Sacrifice, the covers for the upcoming novels feel like a return to the era of a lack of inspiration for Trek covers dominated by floating heads in space. Granted the Titan and Vanguard covers stay true to established motifs (and are well executed, just like their predecessors), but does this mean that from here on out we'll be seeing uninspired ship shots for Voyager's relaunch? The cover for The Romulan War does not, in any way, convey a 'war' to me, not even a cold war; instead it makes me think we're going to be getting a lot of cerebral diplomatic conversations. The Sorrows of Empire's cover is bland, bland, bland - are we on Vulcan? And the cover for The Soul Key just looks cheap.
I guess this just goes to show how spoiled we've been over the last couple of years when it came to gorgeous artwork for our Trek covers.
