$11- Standard plays?

[Stickmn24]

I don't play many sit-and-goes, and I was wondering what peoples' thoughts were on the flop play and on the river play. I don't have any glaring reads on SB... he seems like a decent player who built up a good stack by staying pretty patient. I haven't been playing that many hands, either. Is the flop bet okay? What about the river bluff, given my table image (which might not matter that much anyway)?
