Update time! Despite a super busy week at work - needing to drive 2 hours to and from a new project and working 60 hr weeks, thus leaving me even less hobby time - I managed to finally get some decent work done on both the first contemptor's pose and the finishing touches on the Lord of SKulls.
First up is the dual butcher cannon wielding contemptor. I wanted to have the butcher cannons 'feel' like the enormous weapons they are - thus I opted for the body with the enlarged engine block I created last weekend. Also, as I want as much variety in poses, this one needed to have the right foot in front and lower than the left foot. This fitted well with the pose I imagined the dread to have, having to brace for against the massive recoil the two enormous guns would produce while firing.
The mock up for the pose here is held together mostly with poster buddy, although the knee joint and the lower back and pelvis are glued together. What do you think?

Second is the final final touches of the Lord of Skulls. I sculpted the last muscles surrounding the joints attaching the legs to the 'pelvis' of the beast. These muscles both serve to enhance the whole daemon engine jive, as well as to strengthen the joints structurally. I've been warned both off- and online that these are very weak. I've already driven nails through them for added strength, but I figured some extra surface area would hurt either.

I also finally got my hands on a new bottle of airbrush cleaner, so there's now nothing stopping me from starting painting. Except for real life responsibilities, that is.... 
That's it for today! Hope you like. Feedback as always welcome - and thanks for looking.

@Flint13: Will do Flint! Coming Thursday I took an extra day off and I'll make some pics as I do some extra skinwork on the contemptor. 
@KrautScientist: haha me neither mate! Luckily I can finally start painting now that I have all the grear I need. Hopefully my compressor holds up.
@Barrabas Sogalon: Thanks mate, so glad you like it. I'll take walkers over tracked vehicles any day 
@Dragonlover: The only reason I'd wait with the LoS for next ETL is the points value, but that to me is less important than just getting him done when I want. And I want it now, and lucky for me there's the call of chaos right now!
About the kakaphoni weapons and the 'effect on the casing' you're refering to, I'm not sure what you mean... could you explain - and maybe have suggestions regarding it? Love to have your feedback
