Planetary System

I really like the picture I chose, but I have a couple of concerns. The dots do not appear to be uniform in size. Even in the same colour, there are slightly different sizes which makes the rows uneven. I am having to adjust the rows and this is leaving some space between the rows. I don’t know how the finished picture will look. Also, the glue patch to be used to pick up the dots is very small for the size of the picture. I would like another glue square, if that is possible. I won’t have enough to finish both of my pictures since I have already had to use the glue square from my second picture.
