The answer was, of course, both.
Although with minimal alterations, the female space marine is likely to be finished first.
As the "new" combi-weapons come with 1 bolter and 4 top options, I have cast extra bolter parts to make use of them all (eventually).
The Sanakan Necron is in the process of re-posing. I'm aiming for the ref' pose on the left, with the S-shape of the right.
Selected head from a Dark Eldar Wych, with the top knot removed.
Bonus, late in the day wip.
Miss Space Marine is now on her base.
I cast up a hollow helmet rather than drilling out the solid helmet.
She has now moved to the painting desk.
@DrH fantastic conversions. I have to say that while I love the lady space marine head generally, I absolutely love the beret!
@evilkipper Thanks. The heads came with the berets on. A sprue of 4 from crooked dice that I got from Bad Squiddo Games while picking up other things.
A couple have the hair tied up (like this one), and one comes with a separate ponytail (wasted on a space marine, it wouldn't be seen).
