About this 3D model

This is my second model for a 3d printer and I tried to use my experience with the first model (thanks for all the tips!) to give this one a better start. Updated information will be posted in the Instructions below. It's another little pet monster for the 3D Artist Mag contest and it's supposed to be a decoration item. Please let me know if there are issues with this model, I'll try to fix it. I don't own a 3d printer so I'm not sure if everything is as it should be. Best regards, Andreas
