The first thing I would do is lower your average cmc. So much stuff here is over 5. It wouldn't be a problem since you have a good bit of reanimation, but I'm not seeing any kind of ditch outlet.

You should at least run the creature ramp spells like Wood Elves and Farhaven Elf. Theyre good with the general, would help fix your curve, and can be used for stuff like Skullclamp.

Also, I don't see any kind of ramp. You're playing a lot of high cmc cards...but no ramp. Some of the better ones are actually really cheap. Nature's Lore, Farseek, Cultivate, Kodama's Reach, Skyshroud Claim, Explosive Vegetation, Ranger's Path.
