It is a beautiful piece of LEGO art.
However, to me, the MK1 appeals to me even more than your latest project MK2, as it has more unique head shape and is more bulkier than the last. It could be nice if you could use MK2 as the generic ship for troops, while MK1 for the protagonist ship as it looks like it's more memorable and agile in action.
Anyway, nice, sexy, classic blue-yellowish models!
