Sooo, at a quick glance, I have noticed that you have a few cards that are a bit unnecessary. Stormscape familiar and phyrexian altar are good cards, but I don't think that you will end up needing them. Your mana curve is already pretty low, so I doubt you will have any problems with mana. Also, your deck is significantly more white based than blue but you are keeping the same number of lands. I suggest cutting down on your blue lands, adding more white. The statistics bar can help you figure out the perfect ratio.
EDIT: some spot-removal could be handy for when you are not facing pure aggro
EDIT_2: also think about your deck in terms of win-cons or win conditions. If your main win condition is to over-aggro someone, a good mid-range deck will take you out with ease. Try building it around a specific leader type bird with the others supporting him, not just a mass of creatures.
