tl;dr i think you can go a lot harsher with this, make the textures rugged and dirty and put more contrast into the bump map / pbr whatever the term is

some of the textures feel a lil flat especially around her tiddies, i see whatchu tryin to do and i like it. if you can add a lil more depth to that area, go for the whole corsette idea.

somethin else that bugged me were the shoulders, they also feel a lil flat along with the stripes too
