I've made a bit of progress on the Strike tank: as with all my space marine gear, I'm doing a Blood Raven color scheme. Here is the entire tank base coated + sponge chipped:

Then I added a racing stripe along the side, as a banner onto which to put the raven:

It came out pretty good, except for a bit of overspray despite my overzealous masking. Very fixable though.

I went for a more stylistic raven than the one I did for the Fire Raptor. More of a germanic eagle styled raven. I kinda like it, and I think I'll use it from now on.
