Thank you again. It would be totally cool to be (if I can call it that way) true part of this community and actually help other people, instead of "only" waiting for video reviews if you know what I mean. But as you also mentioned we're just beginners, so I think it's a long road before this happens.
If we speak about posting more stuff, we actually had christmas break so we can say we finished 2014 year by posting two videos on our youtube channel. Now, when the new year started we'll definitely work hard to make a big step forward (not only by working on our voices, but also by posting more videos or even making some small live performances)... becouse as we see, it's worth it
And about the song you posted, we'll definitely look at it!
