I think it's handsome and romantic.
When I was a kid, one of my friends had an older brother named
Sebastian, and my oh my, did it ever seem special when every second guy I knew was called
Mike. I guess I have warm nostalgia for it because of that. Also it reminds me of The Neverending Story and the protagonist
Bastian, so the nostalgic meter just keeps rising.
It is a little unwieldy I suppose. A little fancy.
