Cute picture. The b/w conversion isn't bad, but it is a bit flat...though that's somewhat normal in digital media. I would crop off much of the left side, the negative space isn't doing to much for the image and my eye moves there to see what the pattern on the wall might be. I would probably have taken it so the boy's face was on the right and then have a little more space on the left of the image. Nice, though. Certainly one I'm sure he'll want you to not show his future dates.
Like this edit, but maybe a bit more space on the left.
