The cyborgs remind me of many other 15mm scifi or fantasy "units" (especially of anything half-human: beastmen, aliens or robots). That is: they're a series of only vaguely related miniatures, and as there is only one pose of each type and limited possibilities for conversions or reposing, I wouldn't find them particularly useful for building up into squads or larger forces. If models look like the sculptor got bored while he was making them and moved on… why would they be any more interesting to paint?
Not that I do anything in 15mm, but I'm just saying… sculpt five or ten cohesive miniatures that look more like the same guy standing in different poses, with at least a couple of weapon options, and *then* think about casting them.
The three in first photo are a good example of the idea that you don't need to cast something up just because you sculpted it already.
Struggling to be constructive here… ah, I think the dollies seem to have made a difference? The detail is still blobby and indistinct but the general shapes are more "man in a rubber suit" than "rubber suit in a pile on the floor". So, armatures = good.
Finally, can I ask if you are are working from concept sketches? These figures all seem a little 'made up as you go along' – details seem to have been added simply to fit the space rather than to represent physically sensible equipment and clothing, or proper anatomical details. The end result is that the models end up looking like they are carrying strings of sausages, or sacks full of lard, rather than ammunition pouches, respirators, webbing, armour plating, etc.
