The model has real world scale and can be further subdivided without problems. For the preview it was subdivided one time and the true poly count is shown in the last preview image.
All used textures and maps are included: one texture / diffuse map, one glossy map (invert for roughness), one transparency map, one subsurface map, one subsurface colour map and one normal map. Images measure 4096 x 4096 px. UVs are unwrapped and everything is named properly.
