Swift update here on the vow. Here’s a shot of the 6 titans I’m doing:

So I’m feeling pretty good about finishing this vow in time, with two weeks left. All my titans are built and basecoated.
The Warbringer is finished. I’ve put transfers on and I’m not totally happy with them all, so I might revisit that, but otherwise I think it’s come out pretty well.
The Astorum Warhound is ready for transfers, weathering and basing.
The Penumbral Reaper is virtually ready for basing. I want to do a couple of details like the eyes of Horus. Basing needed, obviously.
The three Mortis hounds are coming along quite nicely. I’ve got them all basecoated so the next thing is some highlighting on the black, red and white areas. Then transers, weathering and basing. I’m giving each one its own pattern on the leg armour, probably to be shown on the right leg. Here are my pairs of designs, all of which need some tidying up. I've found that it definitely looks better if I pick out the rows of rivets in gold, but it's a bit of a painful process as they're so tiny.

The plan is to get all the hounds ready for their transfers and then do that, the splatter mud and basing for them all. My Mortis guys are going to have the same style bases as my Astorum, to show that they’re fighting over the same place.
I did originally plan to do a Mortis Reaver instead of the Warbringer. That’s still in its box. I plan to do another hound and that Reaver for Mortis, so I’ve got a 1750 point force with minimum-sized Mandatum and Ferrox maniples. Self-isolation has given me more time to paint models but less of a need to make them into a field-able army right away. So I’ll probably take a bit of a break from the Mortis army and work on other stuff – like my Psi-Titan and some Aeronautica stuff I’ve recently (and perhaps foolishly) ordered. Oh and I’ve got a load of AT knights to do, if I ever decide what household to go for.
Good luck to everyone else working on the vows, and hope you’re all doing ok generally at this mad time.
