I would share some things to help you improve on this
1) Next time try adding some piano part in the editing it will make your song sound fuller and richer..if you wanna take your recording to next level....
2) Try getting the song edited in the software little to add effects on vocals and instruments ..btw you already have a good voice..but all the singers do that...!!! so don't worry!!
3) Make sure light is very good in the room and it is falling on your face to spotlight you!!!
Try these things next time, you will be good to go,.and i am sure you will be posting great videos in future..all the best :)!!Great work !!
