Singing with my diaphragm/tips/comments on my singing?

Well its not that i don't like it, its that i want to help you improve. First you sound like you use a lot of air, which is good but it sounds too airy to me if that makes any sense. You need some sound to that voice of yours. When you run out of breath and need to breath remember not to force the breath let it happen naturally. Another thing would be to practice some singing warm ups, if you don't know what these are google it.
