Space Cat

Hi there,
Hope y’all are well. I’m interested in making a 3d cat sculpture of space cat. The cat would be looking up in amazement (like in the photo). https://pbs.twimg.com/profile_images/424484505915621376/EOwsjaMZ_400x400.png For the skin / fur, I’d like it to be a Hubble Space Telescope photo of a galaxy. I think I may have to go to a hydro-dipper for that part of the process.
I had found this file ( http://www.thingiverse.com/thing:342783 ) and wondered if it would be possible to edit the head / face / neck.

Can anybody help me bring this project to life? This would be an indoor sculpture; I don’t have any strong feelings at this point of the material of the sculpture (I don’t know enough about different materials).
many thanks!!!
