ok I know sometimes I use in complement photoshop
in the game some details will not be seen
but I noted a detail of the shade and light side
it seems to receive the light in a direction high on the face slightly on the left
the left side of the front should be slightly less dark
and lighting on the top teeth should be the same orientation as the bottom
shadows behind the mask left side too wide
it does not remove anything from your beautiful work and very complex details
this is just a constructive criticism because even to me I find errors in my work
but if it can help
i love seeing people discover and explore
ps: it may be that my text is incomprehensible I am French speaking so use a translator
