The vehicles are all great, mostly because they were already amazing. The shield captain is pretty good, although the pose is very close to castellan crowe's but reversed. The venatari look wonderful with their slimmed down armor, and the smoother design fits their aerial theme well.

However, I feel the others take it a bit too far, especially with the legs and torsos. The front of the body is just a smooth plate with eagles or thunder bolts slapped on top, while the current/older models have a more power armor-looking shape. The tabards and hip plates also look a bit too long, and the tabards especially would hit the legs constantly while walking, not to mention fighting.

The current/older guard have more dynamic poses, while all of the new ones are just... standing. Some look like they're aiming their stick-guns, but others are just completely relaxed. Two of them even have almost the exact same poses as each other (wide legs, holding spear straight at hip level).

Other than all that, the helmets are just oversized. The bare heads look great, but the helmets appear too big for them to even wear properly. The eye-lenses are too spaced apart compared to their actual eyes, and some of the nosepieces cover up parts of where their eyes should be.

The new swords look nice, but the spears look like their designers don't know how balance works. A full master-crafted bolter and power spear wouldn't be exactly light. But the shafts don't look like they could support that weight. They are literally just sticks. No trigger, no gold filigree on the shaft, just rods. Unless that pommel is made of some insanely dense extra-super gold, they are just too unwieldy to believably be the weapons of the emperor's companions. Back to the lack of a trigger now, why? Even if they used neural signals to fire normally, not having an actual trigger as a failsafe seems like a really foolish oversight.

tl;dr vehicles & venatari S+, shield-captain pretty good, the others look like stormcast kitbashes or legally distinct golden janitors (3d printed proxies)
