I know it's not perfect but I tried I let my little sister sing it hahaha
I know the sound is not awsome, but I think pretty good for just a room recording,
I recorded everything with the mic of my computer

Actually this is pretty good. Everything links up here - this has an overall intimate quality that supports the theme of the song pretty well. Your sister's voice, the way you are playing the instruments, everything has a charming quality that just works for me. The production of this is pretty good - hard to believe you did this using only a computer mic.

Tnks man, What the thing is, I have a shure mic, but it's mono like every mic, but the input of my comp is stereo so the sound only comes from one side   haha

As Battlecat highlighted the song has a nice intimate quality, your sisters voice is great, with a few lessons she can work on getting those high notes to cut through better, never-the-less I still like it.
Love the vocals just before and during the harmony backing vox.

Just work on an outro.

For one mic and no interface you have done a great job on the production.

When I first started out with no cash, I used an old Tape multitracker as a mixer/interface. I purchased a battery operated condenser mic, the AKG1000s, and plugged that into the multitracker.

Mind you there are some great plug-ins now you can create analogue/tube sounds, many are free, but still best to get an interface/preamp

Welcome To Bandamp too!!!!

This is good! Your sister has a great voice

I'm very impressed by quality of recording and the talent you guys have.
It's rough and ready, innocent and pure.
Really enjoying this. I can hear it could do with a 'tiding up' but yet it is lovely as it is.
Keep at it .. both of you have a lot of talent to develop.

Thanks man, my little sister is really shy with singin, so I put here in my room, me and here alone, and I was actually suprised!! So I hope these comment will give here some confidents!!
