You have sufficient mana. I would recommend 34 lands and 10 pieces of mana ramp. I would count
Awakening Zone as mana ramp. This gives you 11 pieces of ramp. So you could cut about 4 lands. I would suggest cutting:
Grasslands - you shouldn't need a slow fetch in a 2-color deck with green.
At least one of the hideaway lands.
Consider cutting any other land that could enter tapped, like
Khalni Garden. Do you really NEED that 0/1
Plant? Is it really worth a delayed land drop?
If you've still got a land or two to cut after that, I would go with basic
Plains. Skew your mana base slightly toward green. Because all your early drop mana ramp is mono-green. You want to be able to realiably cast the mana ramp in the early game.
Hope this helps.
