Composing but one problem

[kaiwin]

Ehh.. How do I put this. I have a section that sounds familiar but I don't know if is actually from another piece.. if that makes any sense...  But I doubt it... Is it ok if it is?
I'm confused....

eh...hard to say.  there is so much our ears have heard that it's hard to say who came up with what.  If you make it big with this piece then i may worry a bit, but for now don't worry!
