Video Game pinup art. Lara Croft, Morrigan, or Cortana?

I'm going to do another set of video game pinup girls, but I' haven't decided who to paint yet.  I did a rough sketch based on a classic pinup pose and then sketched a few options up.  I'll pull one of these to finish as well as another pose, but I'm really torn about who to represent.

This was the blank pinup pose

cortana from halo

lara croft from tomb raider

morrigan aensland from dark stalkers/vampire savior

Whatever the choice, I'll litter the final with references to the game and probably tweak out the costumes a little bit so that it isn't so plain vanilla and boring.  Although now that I think about it, it's almost impossible to make Cortana not boring.  What a terrible design.

Maybe I should pick that one and try to make her as interesting as possible as a challenge.  Looking at Halo... the only thing they got right were the helmets and warthogs.  I'll bet I could make her look good, but is it really worth all that love?

Bahhh who knows.

cheers,
