finished product in an hour.
coming from someone who makes every texture in ussually an hour if speed isnt a strong trait in your art. Work on the basics. know your color theory. know where the darks and the lights will go just by looking at the shape of the object your drawing
after you work on those traits the speed will come naturally
walk before you run
I can't really see where the horror part is, other than the scar and unusual skin tan there isn't any horror in it, as the expression he's doing looks really bland and dull. Making the eyes squinting with an opened mouth would probably add to the horror theme.
But none the less, it looks really nice with that amazing mapping you've got going on! Nice job, keep it up o7
