i did not hear you beforehand, so i do not know if you have improved. but to be honest, unfortunately, no, i do not think you can sing. there were serious pitch problems, and you also lack your own vocal style. i don't want to be mean, but despite the pitch problems, i heard no hint of soul or personal expression in your singing, and if i had, my opinion would be different. i hope you don't take this to heart, as i do not want to upset you or ruin your day. you can sing along to a melody just fine, but i do not believe you could sing professionally, that's all.
