Nothing I would really change. I thought I would also try some different filaments as I had to see how they would print. The Glow in the Dark looks great!! I also thought on trying to cut down on print time, so I decided to try the print on a smaller scale. At some point I do want to try this in ABS and use the smoothing technique. I think it would add to the look of the Skull. I would recommend this to anyone to print.
