Looking good, seems very accurate. Try to get some wip shots up next time, its not as fun when we can't see the process!
One thing I noticed, is that the half circle shape on the baseplate, where it latches to camera itself is too soft and not quite accurate, I noticed the same thing here; http://www.polycount.com/forum/showthread.php?t=78362
You may just want to reread my last couple posts there.
If this was to be baked down to a low res model as a game asset, I would say a lot of your edges are too hard, but its sort of up to you if you'd like to model with that mentality.
 Oh one more thing, with the leather chunk, you have nice soft bevels for the intersections on most areas, but that half circle shape, and the strap lugs its just a straight up intersection. Would be nice to have that modeled there as well so it doesn't look tacked on.
