Girl playing violin on the BART

I took this on the train to San Francisco one day. I noticed

afterwards that the person in front of me jumped into the frame. How

very rude. Thanks in advance for any comments.

Interesting capture. Representing the Bay Area!

I think you should crop out that black splotch that take up most of the right side of this photo. It almost looks like development error or something. Best not to have it distracting your viewer.

No doubt you're using high film speeds here (or a wide open aperture). This exposure isn't bad, given the circumstances, but I bet you could get a little more tonality if you tweaked your exposure and your developer.
