Lovely work all around. The one in the bottom right has been one of my favorite 40k pieces ever since I first saw it floating around the interwebs. The level of work you do is just stunning and it's always a treat to see a new deviation from you float my way. Keep on keeping on. The Emperor protects.
The first one kinda reminds me of you, especially from back when you had your hair short (it's so long now!! 8o ) But you do good facial variations so it doesn't surprise me many don't have obvious similarities since they're all different owo
