A very well done commuter. Can the rear reflectors be seen from behind, or are you panniers blocking them (it looks like they are blocked from view from behind)? You need a back light that can be seen from at least 200' behind imo, for safety reasons to keep from getting ran over. Panniers with the back ends covered in reflective tape can probably achieve the same end.
Edit: I'd rather my next search for motorized bike fatalities to only show up stuff a few years old. They happen, a lot from fender or wheel failure... keep an eye on those.
Most of the rest happens from folks turning in front of you, they just see a bike coming, so they judge your speed based off of a slow bicycle. Make sure your brakes are good to stop from 50 mph in 30 feet.
