Hallelujah (cover) - editing feedback appreciated

Hello guys!

Pretty excited now that I have made my first video with my new audiobox and editing software.
Now I wonder from you guys with more experince, how to improve the sound and videos further?

I liked your cover a lot! one small tip though is it seems like your holding back a little.. i used to hold back but then i was like... what am i doing? i can take as many takes as i want.. ill just belt it out and mean what im singing because who cares if my voice cracks. Other than that. good!
