Space Marine squad

Last week Cathy came back from town with a gift for me - issue 1 of a new Games Workshop "Warhammer 40,000" partwork that included a couple of models to build. 

I have a habit of buying the cheap first issue of these partworks. The subsequent issues are always more expensive and they mount up way too fast. But the first issues are decent value. This one came with a Space Marine captain and a big monster called a Tyranid for him to fight. 

Its an impressive figure. He has a sweeping cloak and is set on a moulded base.

Combined with the other Space Marines I've acquired (mainly from other partworks), I've got the makings of a little squad.

Now the big question is, what colours do I paint them? Do I create my own 'chapter' or go for a more traditional colour scheme?

The Tyranid meanwhile has joined my pile of shame...
