Hey man! I'm really enjoying that briefing. I have a couple of suggestions though.
On Aldaris I feel like his hood should move a little bit like cloth. I like how it doesn't move like it's a piece of the head but maybe if it follows the movements just slightly.
Also seeing him with Zergund's portrait portrait I realize his texture might be slightly too smooth. Maybe add a little rough effect to his skin.
The HT also looks amazing and I like the slow movement so much! The wide arms feel so right too. I made one with the skirt a while back and with more subdued arm animation and didn't realize they would look so good out like that.
Good work man!
