I'm not sure about the texture you've used for the rough. It just doesn't seem to sit very well with the other textures
A few people have said that but there hasn't really been many suggestions as to what to do with it.
I took the project over from somebody else and most of the artwork was already done. I can't really do much in the way of artwork myself. Let's just say that adding the stripes exhibits the full extent of my artistic ability.
Did you mention before that your cup is a texture on the green? Or is it an actual hole in the geometry?
Its a quad, aligned to the green.
