Looking at it all together, I fear you're spinning your wheels when trying to make stuff. It often looks the same. Male face with prominent cheekbones and mouth deep in shadow. You've varied it a bit, but it's still often the same look. It just reminds me of where I am now, just making what I know I can, rather than pushing myself to try something truly new.
I really like the one of Tremulant's character, I wish you would have finished that since you usually do so well with warped spiral like musculature.
