Glad to see you still up and about fss. You're low poly models are looking as spiffy as ever. xD
If I may suggest, if you do go about posing these for promotional art/char bio renders, possibly add in a bit of shading to help flesh out the form. Particularly shots like the center ones. It's a bit confusing to tell where the arm arms end and the legs/thighs start.
But for ingame poses, which I presume are those on the left and right ends, I think the no shading works well. Their pose and silhouette help convey what form is what limb. Though it could help maybe adding a slight degree of shade on the opposing limb to help differentiate left from right from the viewer. Heck if you could you could paint the shading on like how it's done now a days to help flesh out the form even further.
But then again, it is your art direction and all. Just sharing my thoughts. :3
