Everyone should do vocal training! so keep at it!

You need to work on your support with your diaghram (when you are exhaling, i.e. singing, not when inhaling, then you need to relax the muscles), Practice scales to improve your pitch as it is a bit flat at a lot of places. Try to keep an open relaxed throat, relax in your chest and neck muscles. Breathe with your stomach if that makes sense. And last but not least, have fun no one becomes a world class singer overnight, so keep up the good work!
