Hey man, I totally feel ya. So many damn views but no input haha.
Okay, to start, it looks like your slaneshi symbol is off-center.
I really like the idea of including iconography from all of the gods and wonder if you might paint it in a manner that looks like each of the areas you've stamped with an emblem are colored to match their patron's heraldry.
I think the hades gun needs some sort of receiver casing around it. It looks wimpy
Nice kleava. Needs bloooood. (and maybe some spiked knuckles on the fist?)
That being said, I really like what you've done with the 'zerk in forced stasis as a pilot, but (as a biased Khorne-luvva) wonder why it isn't just a fully Khornate engine, or in terms of what I wager you're going for, why it isn't a vanilla
CSM? I think this area could benefit from more wiring/tubing as well.
Edit: To further expand on this, what I mean is, why not a counts-as
LOS that isn't biased toward Khorne? I feel that the glyphs and the 'zerk present a conflicting theme and one or the other would pull it off proppa.
But, of course, do as you so please
As for things you might add to fill out the model:
The linkage between the treads seems a little too bare. Maybe bulk out the axles, add in something that looks like its propelling the tracks, or maybe just some armor plating.
I think some plasticard armor paneling would do leagues to make it look like something more imperial as well.
The lower arms need.... something...
Maybe hydraulic lines or wiring? Maybe some armor?
Make da top armz BIGGA
Overall, you've done some really cool stuff so far. Keep up the project!
