Island of Hope

One of the summer projects for AP studio art, I have to do 4 projects total over the summer, and this is another one of those. it's was supposed to be how we think technology relates to the natural world, so this is what I did. It reminds me of Wall-E XD
Chalk pastels...they're soooo messy D: I used a fixative, but it still spreads if I'm not careful, is there any other way to keep it from coming off?
