Newer magic player wanting help with Gruul deck.

I've been playing digital magic (duel of the planeswalkers) since Magic 2012 came out. Recently I've started to collect real cards rather than only playing digital. I bought the 2013 and 2014 deck builder toolkit to start out. Since then I've bought a decent amount of booster packs, gone to card shops and bought single cards that they had, and bought a few pre-made decks to take apart and use the good cards. Since then I've only played with close friends never at an event or anything like that, though I want to. I was wanting feedback on my Gruul deck that I made and wanted to know how to improve upon it. Here is the direct link to the deck http://deckbox.org/sets/540437
