Doesn't look too shabby. :)
A couple things off the top of my head:
If the build is going to be used for outdoor farming (it wasn't quite clear from your title), it might be nice to pick up Pathfinding. You can probably drop 2 points out of something else, and the mounted speed boost is really nice for riding around farming herbs and such.
Improved Revive Pet is always kind of a tricky choice. You certainly have the points to spare to pick it up, the question is how often you will actually need to rez your pet in combat--and how often you'll survive long enough to get the cast off. If you find your pet dying a lot, then it's a great talent to grab, especially when paired with the revive pet minor glyph. On the other hand, if your pet is fairly sturdy, one or more of those points might be better spent elsewhere, like filling up Improved Mend Pet and possibly Go For The Throat depending on gear.
Which glyphs are you planning on using for this spec?
