Hi Poca, Thanks! Your artwork is really good. I use ZBrush for my models too. I'm self taught but my process is basically- Model, Hollow, Paint, Duplicate, ZRemesh the duplicate at a low polycount say 5000, UV map the new mesh, subdivide the new mesh back to a few million polys, project the original model detail onto the duplicate, create a texture map from the polypaint, Decimation Master with keep UVs down to 1 million polys, then 3D Print Export from the ZPlugin Menu. You'll easily find more info about each stage online if you search. It takes a while to master but it's worth it. Good luck!
