I'll start with what I liked about this. It's really sad in the fact that Ralph and Gina know it's the end of the world and they can't tell their daughter. It's really cute how Ralph tries to make the day as best as possible for his daughter. I can totally put myself in his position and the story teaches a great lesson. =)
However, the first thing I noticed was that the backgroungd made it really hard to read. Maybe next time, don't use a pattern behind the words? Another thing: don't be afraid to get into more detail. Maybe some more sensory detail or something to make the emotions that much stronger.
Overall, I really liked this. Great job! Good luck, and stay tuned for the results around February 15. =D
