Thanks guys, it felt like an accomplishment of sorts as as much as it makes me nervous every time I move the model having some heft to it certainly helps it stand out some more
The milliput filler turned out nicely, hits that nice spot where you probably wouldn't realise it was there
I also think the extra variation on the carapace lines worked so I'll be mixing it up on future larger models too.
The stealers are progressing, those all those arms and fingers weren't fun! I'm sure I've missed some lines in the cleaning somewhere...

Model wise I'm sticking to the claws, in part as six of these are the old Battle for Macragge models with no options but also because I much prefer the look. These are Genestealers to me
Plus as a free option that takes nothing away I consider Scything Talons for stealers to be akin to grenades or bolt pistols - if everyone has them and they cost nothing who's going to mind? I did give them two Acid Maw heads though, got to do that right 
I have a couple of weeks to finish the list, should be possible. I hope to get the base colours done this weekend so I can finish them off in the week, and the same again for the Hormagaunts. The eyes and bases for other models should be able to squeeze in between...
