The crop is a bit too close on the left, it looks awkward. The lighting is good, but I'm not keen on the border. A white one would have worked better I think.
Nice composition of a simple subject. I think this photo would benefit from a bit more contrast, though it does look pretty good in subdued tones as well. And I think the border you chose actually does a good job of enhancing the photo, rather than detracting from it.
