upon looking at your image i see you did not compensate for the main problems of the razor thorn but it's still a good image and if i had not looked closer i would have not noticed. a good solution to try as it works for me as i got something on the way that uses it is to have a geoshell with 0 distance from the character then have the geoshell and your character selected and then apply the skin you want to use + the eye color you want to use and then hide the character and your good to go.
