I'm probably being mean but the longer I look at the profile of the high-nacelle version the more I think it resembles a hood ornament :D although now that I think about it having a starship model as a hood ornament would be pretty damn awesome (needless to say it would be stolen within the first two hours of buying said ornament.) :DThe profile of the nacelle-down version however reminds me of the runabouts used in the shows, just scaled up to full starship size and aesthetics.
