So, November.
I slacked off a bit around the start of the month and went a couple of weeks without painting anything. When I finally did get around to tackling this second formation of Forge Knights, they took over another week to get finished. And to be honest, I'm not all that happy with them. They're not bad, but some of the highlighting is a bit sloppy in places. For some reason I really didn't enjoy painting these much. Still, here they are:

Having taken until yesterday to finish painting the Knights, I then made up for my slackness by also painting this Warlord in its entirety the same day. I'm a lot happier with this model.

At 400 points for the Knights and 900 for the Warlord, that's 1300 points painted this month, which brings me up to schedule. It also means that this army is now the same points value as both my Eldar and Chaos Marines at 6,125.
So how's the schedule looking?
August: 2 x Warhounds (550 individually or 500 as a pair) - DONE!
September: Warlord (850), Reaver (650) - (1500) - DONE!
October: Forge Knights (400), Reaver (675), 2x Warhounds (500) - (1575) - DONE!
November: Forge Knights (400), Warlord (900) - (1300) - DONE!
December: Reaver (725), Reaver (675) - (1400)
I'm also thinking of extending this project for a sixth month, painting another two Reavers in January. That'd bring me up to a round 9,000 points, which would seem like a good point to stop.
