Cool!
I'm not used to this kind of singing but as the song progresses I catch the rythm and gradually enjoy it more and more - until it stops :\
I have two suggetions that are a matter of my own taste of course:
In the first song the backround voices could be slightly more quiet and become louder at certain points. A small fade out of the voice at the end would reduce the sudden feeling that I want more
I like to play with video editing programs creating small videos and I really enjoy this creative process as you do I suppose. At the past I overdone it with a video that (almost) became an obsession. I was waking up in the middle of the night for example just to slightly change the duration of a transition effect between two scenes
Have this in mind please and don't change your sleeping schedule
Two likes for the first two songs!
