Having spent some serious time looking through the CSM codex since last outage, I find myself converted to the creed of the flamerspam. Combi-flamers; Havocs and/or Chosen loaded up with flamers and meltas; Noise Champions and Lucius with Doom Sirens; Warpsmith with BBoS; etc. Then tank shock enemies (with destroyer blades and dirge casters on my Rhinos) into tight bunches and torch the grouped enemies, and perhaps include Slaaneshi daemons with Pavane... the ideas running through my brain give me no rest. I think I could go on in this vein for some time.
In short, though, I love what you're doing here even more.
Re: latest pics, I'd have to say the symbol on the cloak on the DV lord looks a little patchy. Other than that, good stuff.
6th Edition has been extremely kind to flamers! The Pyre began life as a modelling project and sort of a joke to see how many flame templates I could pack into one army, and it's become something (even before the new Codex) something that was extremely capable on the tabletop.
While it's definitely all well and good to bunch your enemies up and set them on fire (especially with the -wonderful- Burning Brand) I've found that flamers are the pinnacle of defensive weapons. You can do a surprising amount of damage on overwatch with a pair of flamers and a combi-flamer plus seven rapid-firing bolters, and follow that up with two attacks a model from your Chaos Space Marine troopers (you bought extra close combat weapons, right? Right.) it's been my experience that short of something like a Terminator squad, any unit that closes to within a foot of one of my Pyre squads is in a -lot- of trouble.
I've also found corralling my opponent using Rhinos, terrain, and my own units and then deep striking terminators almost on top of them has extremely effective results-- my unit of Terminators has killed a 15-man death company unit in one shooting phase-- it's amazing what happens when you hit them with six combi-flamers (as opposed to eight, as not all will be able to connect from the deep strike formation, but you can set it up so you get six) and two heavy flamers on a tightly-packed unit...
I've just been laughing maniacally since the new Codex came out, though. My Lord has reaped a bloody toll with the Burning Brand... people still aren't quite used to having to spread out at close range because flamers weren't popular for basically three editions, so I've gotten a disproportionately high number of hits... my lord has killed nine of ten Space Marines in one fell swoop with the Brand, and then jumped in and murdered the Sergeant in close combat.
Fun fact regarding Chaos Artifacts-- Grenades are weapons (BRB weapons section). I'll leave you to think about that one...
So here's the complete 1850-point army (although now that I look at the pictures, I forgot to put one Rhino on the display board-- there are three). The spawn is on the board just because... it's not actually in the list, it's just handy for the unfortunate number of times my Lord has rolled Spawndom on the Chaos Boon table...
I do have another 1x2' section for the display board that's a crater-strewn, flame, bathed battlefield for when I want to enter the army in Armies on Parade, and spread the squads out a bit. But for general use, the building section does what I need it to do in terms of being a good tournament tray and display board. Not the greatest pictures-- it's hard to get a focused picture of something as big as this using an iphone, but you get the idea!
The Rhinos get parked in the back of the building for ease of transport around the game room-- also, nobody cares about the rhinos particularly when checking out the army as a whole...haha... with the full 2x2 board, they're out dropping off squads in the blasted battlezone section of the board (no pictures of that yet, since it's not finished) though. You can see them through the windows in some of the pictures though!
As for some other stuff I've been working on that doesn't make it into the 1850-point list--
I really liked the new Aspiring Champion model, so I picked one up.
And you pretty much have to have a Daemon Prince handy these days for the 8% chance you have of a champion becoming a Daemon Prince over the course of the game from the Dark Apotheosis result on the Chaos Boon table. So, I have an awesome model for when that happens now.
