You should get down to 60 Cards, then you should get important cards 4 times in your deck.
I saw that your Green Creatures are always to expensive and to weak, so in my opinion if you want to stay at your elemental theme you should cut green and get some fast red creatures and some nice
burn spells and play just red.
There are also some nice Elemental Warriors in the Lorwyn-Cycle.
If you want to stay at Red Green you should overthink your concept. Green elementals are always expensive. So you need some Ramp. i.e.
Arbor Elf.
When you play two colored you should get some two-colored Lands in your deck.
