really good for a first head texture. I like the style of the face. Needs more colors and it doesn't really fill up the head enough. Could be better but still good, especially for a first.
Good job like the design but there are some things that could make it even better
if you remove those black lines of the face and add some shading instead it would be better
the back of the head i think would use some more detail
anyway very good head for your first 9/10
