At the risk of being told off by Herschel I'm going to suggest an alternative concept ranger, although in my defence Mercurius did mention the word Hybrid in the Original Post. This is the build my wife switched to after growing bored with her Twin Striker ... err ... I mean Bow Ranger.
The Build is a Ranger/Shaman Hybrid. The Bow Ranger can quite often stand way back and nail things hard from as far away as possible. They don't have much to do with minor actions except Quarry. And quite often they can don't even need to take a move action.
This Ranger Shaman can still hit nearly just as hard, but swaps out a minimum of Striker Powers for Leader powers that use your Spirit to make the whole team hit harder. And to be honest I think sometimes it's just nice to take a break from 'Thumba Thumba Thumba' ... you're dead.
My wife's spirit companions are the restless spirits of her two younger brothers, whose death she feels responsible for. She has taken the Watcher Spirit OAtk power so when a creature provokes an OA from her spirit her other brother possesses the Sorceress and channels his ire through her arcane power. Alot of 'Puppet, do my bidding!' goes on and the the sorceress loves it. I don't know if you have any other ranged attackers in your group. If not you can swap the Hybrid Talent for the Bear Shaman OAtk power which does WIS dmg and gives surgeless healing, which is fairly cool too.
Oh I forgot to mention 1/encounter 2 target heal and Speak With Spirits power for out of combat goodness!
Something to chew on before you finalise your PC.
level 11
Elf, Ranger|Shaman, Keen Eagle: When you APoint you get a second spirit for a turn. You can shoot around corners, drawing line of sight from spirit and you get an encounter power that lets your allies score a critical hit from 16 -20 (They will love you). Sharpshooter is still a good option for you, but I thought I'd show another option for you here

FEATS
Level 1: Weapon Proficiency (Greatbow)
Level 2: Weapon Focus (Bow)
Level 4: Bow Expertise
Level 6: Hybrid Talent: Use this to gain a melee range Spirit OAtk Power so you can be in the middle of combat even when you're not.
Level 8: Shadow Initiate: You can use Assassins implements (weapons they are proficient with). This means you can use your Bow as your implement, which avoids a WHOLE LOT of hassles with implement powers, switching from bow and Implement. Plus Stealth. Plus 2 Shrouds per combat. Sweet deal!
Level 10: Lethal Hunter
Level 11: Nimble Spirit: Call Spirit as a Free Action. This allows you to reposition your Spirit anywhere on the battlefield with a minor action to recall it and Free action to summon it back in the most annoying place possible. This gives you an awesome control element to play with if you use it wisely. For example, try and flank someone up against a wall with a Spirit Companion next to them or get past your Fighter in a 10' wide hall with your Companion next to them
POWERS
Hybrid at-will 1: Twin Strike
Hybrid at-will 1: Claws of the Eagle: When you can't attack, let's say your blinded for example, you can give your attack to the strongest person on the team and if it hits the enemy Grants Combat Adv which everyone benefits from.
Hybrid encounter 1: Stormhawk's Fury: Vs Fort is the only bad thing about this one, (although you do have elven precision) but if it lands any creature next to your Spirit basically has Vulnerable 5 to any damage received. If you coordinate well with other PCs this can stack up alarmingly quickly.
Hybrid daily 1: Spirit of the Healing Flood: An AMAZING healing power to have up your sleeve. Gives everyone in the team a Get Out of Jail Free Card. And a Burst 5 attack ain't too shabby either.
Hybrid utility 2: Invigorating Stride
Hybrid encounter 3: Disruptive Strike
Hybrid daily 5: Spitting-Cobra Stance
Hybrid utility 6: Hearth Spirit: Surgeless Healing and now everyone is a Dwarf!
Hybrid encounter 7: Biting Volley
Hybrid daily 9: Attacks on the Run
Hybrid utility 10: Hunter's Thorn Trap
