About this 3D model

Creature for a scifi setting I'm currently developing, printed in 15mm scale (as shown with the excellent Khurasan models). Working on ways to get the detail to come in and reduce the extrusion lines. Considering a .5 layer height... Model was designed in Sculptris and TinkerCAD. https://tinkercad.com/things/kp6iFaSVc5b-waste-crawler-multiverse15mm
