It's going and going and going and nothing more...
I'm sorry, but this song is very, very boring. In the beginning everything is all right. I'm waiting for something, but it repeat again. You've repeated this harmony for about 30 times, so every change in the melody doesn't change anything. You need to work on lot of things, like harmony, melody and form. I hope you will take my advices seriously. 3/10 because it's your first piece for piano. Good luck with music!
