Nex- I love how you've done the scars, they bring a log of definition to his face ^^ I feel like the inner ear is lacking some detail but I could be wrong.
Atomic Blue- Wow, that's turning out really good! I love the different colors of highlights.
Dia.- If I were you'd I'd avoid any blur tool for blending shading since it doesn't blend, it usually just drags the color around. I really like that little tuft of hair showing though xD
Silent Symphony- I'd avoid using any red on lips unless it's lipstick if I were you, unless it's blended nicely. Also, using thinner or colored lines may make the drawing look smoother, especially on the hair.

I'm most proud of the shading I think x3
Also, I did this yesterday:
