A million times better
Get the hair done more(I know you already said you were but ye)
Add more dirt make it blend more with the hair than just throwing it on top of it
Add more to the eyebrows, still look like they're floating
I'd completely re-do the mouth, I like the idea but doesn't look to good
Ears look weird
Add more shading to the top of the head, make it shinier like a bald mans head
Shading of the right side of the nose looks really weird
Shading on the bottom of the hair line thing stuff looks weird
Shading of the top of the hair line looks off, you have hair going sideways and stuff, that doesn't look to good either
Mud on the face looks fake/bad just looks like you drew it on separately then c/p it on top of the face, doesn't really go with the face
same for the mud on the top of the head and in the beard
That's all I could think of
