Nice voice. Really the only advice any singer needs is to find a good vocal coach. Support and breath control are pretty much the hardest to master if pitch is not a problem, which it is not for you. Proper support and voice placement will greatly improve your power and resonance. I can hear at times that you push from your throat instead of your center which closes off your sound...I know cuz I do the same thing. Your accent makes it hard for my american ears to understand some of the words, so maybe someone who can also help you tone down your accent, if that's something you want to do.
