I love Star Wars, not as much as Dr Who, but it comes next as a favourite. I decided that after I had done my Dr Who Galaxy Painting, I should also do a galaxy scene related to Star Wars too. My mum cut out a Death Star Template which I used for a rough outline and then painted on top too. I did this after I had done the background a galaxy scene and allowed to dry first. My previous post will show you the method I used which was the same. http://artyprincessblog.blogspot.co.uk/2017/02/dr-who-tardis-galaxy-acrylic-painting.html
A photo of my Dr Who Painting is below, using similar method.
