Raspera (Peramodel2) have a Yellow-throated Bunting if that's the same bird, but Your repainted Sparrow actually looks better than their offering. Yours doesn't have a crest though.

I collect paper bird models from all over the world. I'd appreciate it if you would quote the url for the sparrow you based this on ... so I can check if there are any birds there that I don't have. A copy of your re-paint would be nice too.
