Ok, first of all, I think it needs to be said - ditch the strength angle. It's really not helping you. It only boosts your melee and that's just worthless for a hunter.
You're beast mastery, so stacking up on some more stamina will be helpful, since your pet will scale with it. Also look out for gear with attack power stats. You want a lot of that. Seriously, seek it out like it's the best cake you'll ever have, if only you can get it.
Agility will be another one to boost as a hunter. If you were a survivalist hunter, you'd want to collect that stuff like it's going out of production. As a BM hunter, though, get lots if you can but really focus on buffing your AP. One of your trinkets has some, which is great. Keep that up.
Spirit is pretty useless too but you haven't stocked up on that, thankfully. It's really the strength that you'll want to ditch and replace.
I'm not a fan of the Spirit Bond talent. That's just personal preference though. Some people really love it. You've grabbed a lot of the great talents in the BM tree, which is nice to see. I happen to really like having Improved Mend Pet, given the greatly reduced casting time and mana cost.
Also think about where else you'd like to spill into outside that tree. Survival offers some great utility boosts, while Marksmanship will help to boost your personal dps. Each have their positives.
