I already have a full-body sculpt saved as an .stl file. I will share that file together with a clear reference photo of the pose and styling I now want. Your task is to reshape the model so it matches the image as closely as possible, focusing first on the face and head, then carrying the same proportional corrections through the rest of the figure. This will involve both modifying existing proportions and adding or removing fine details where the reference shows something different. There are no fixed measurements to follow—faithful visual matching to the supplied picture is the benchmark—so feel free to use ZBrush, Blender, Meshmixer, or any software you prefer. Once complete, return the updated sculpt in .stl (and, if you wish, your native project file) ready for print or further rigging. I’ll review by overlaying the new model on the reference; if the silhouette, facial likeness, and surface details line up, the job is done.
