Welcome to mtgsalvation! For the most feedback, I suggest you post your decklist in the multiplayer commander decklist section of the forums, located here. From there, people can review your list directly and give you feedback.
Also, for ideas about Oloro decks, those same Mutiplayer Commander Decklists should have a number of different Oloro lists, which might help give you some ideas about what direction to take your own list. I found a primer list, located here, which might be helpful - primers are decklists and additional information that is meant to help a player thinking about trying out a particular decklist or commander. You can look through the other decklists for other Oloro decks.
You also need moar removal, especially instant-speed removal.

Card advantage is not the same thing as card draw. Something for 2B cannot be strictly worse than something for BBB or 3BB. If you're taking out Swords to Plowshares for Plummet, you're a fool. Stop doing these things!

You're missing a lot of potential win conditions. You have Sanguine Bond, but not Exquisite Blood.
You also need moar removal, especially instant-speed removal.
