Very cool!  It has sort of an "Ash Grove"/Colonial feel to it!  

What a lot of people don't realize, is that writing new material actually aids us in our learning process. It helps us understand & remember different scales & keys in a manner that is fun!  

I'm sure there was a point where you were trying different notes that didn't sound right. For a beginner, that's the first little baby step to learning something as complex as keys or accidentals! 

I've wrote a ton of easy pieces that helped me with playing scales. It pretty cool to see them evolve as my ability & knowledge grow!
