This looks great! If I could make one more recommendation, I would just ask if you could make the continents a bit closer together and more "one". We really want to emphasize that these continents are one! Thanks for your submission!
We think this submission would be much stronger if you veered away from the child's drawing approach and cleaned it up to a more professional look. Also, notice submission #69's (ranked 1st) drawing of Pangea, we are looking for something closer to that when we talk about the continents being together. Good luck!
