Nice! You could perhaps improve this by adding a heatsink because someone might try to use it for something else instead of driving an LED and might end up frying the linear regulator - furthermore you could add a small ceramic capacitor on the end as their fast switching speed would help the electrolytic capacitors and reduce ripple in the output.
