The proccess was firstly sculp the model in high quality with big detail, however this model does not have a practical use beyond  to a concept purpose. This fact after the model was exported to different software like Maya and did a Retopology, thanks to Zremesh this could be automatic, it is not complete accurante but help to do the production faster.
