Alien Skull Bust

Alien skull for making a cool shelf decoration... Made this from combining two other models in Blender and sculpted the face on the skull to match one I saw on the Norwegian tv channel TV2 in the TV-series “Kids In Crime”. I printed in PLA with 0.2 level height and 5% infill. Possibly not super optimized mesh, but not problems reported in Cura Slicer, and it prints without problems. Please write a comment with tips to how I can make it more optimized. UPDATE: Added a new version that are slightly modified in the shape and has are better optimized… Please post a make and let me see how you display it!
