I think u are way to low on spells and to high on creatures...you don't have many ways of dealing with things your opponent does, it looks cool, but id suggest cutting quite a few creatures to even out your spells a bit more so u have more versatility. as it is, u better hope u get PERFECT draws so u can keep playing.
almost all decks need a Draw mechanic/Spell of some kind, maybe I'm overlooking something but I don't see one here? you need them to keep the temp up, and if ur doing for a deck where u want to put tons of pressure on them (agro) then you need to be drawing the cards so u can keep putting on that pressure. otherwise u will stall out if u cant get rid of them right away.
