Well I had a really good idea for this challenge that I have been drawing all day but then change it at the last minute that starting make a few buildings, then came up with a one storie buliding, after about an hour of playing around alot with it made another two storie building and then made a big building of which you see, then made another big building with different colours (mostly blue). Then create a little flashing animation of which I thought aliens would have flashing buildings, I know its not that creative but oh well.

26 colours.
