They look good, and I think you're on the right track.
Next time try foiling with a little beer (or other liquid), and bump the temp up to around 300° or so for the last hour or so (after a good bark has already developed), and see if you like it. I prefer the end result better, especially with beef ribs as they really seem to benefit from the braise. It gets them good and tender and the bark continues to darken.
