Hey Fourleaf,
not bad for your first time it looks really good few things come to mind for me.
1) if you have an iphone 4/4s/5/5s/5c/6 get an app called filmic pro it will get your videos looking much better its only 5 bucks i believe.
2) try doing different angles like do the angel you did then maybe looking from the ground up and maybe like over the shoulder and things like that just experiment.
3) lastly try changing the background ( you dont have to even leave your backyard just move around when you change the angels).
rather then that keep it up i liked it, the video was short sweet and kept me interested keep going.
