Varus God

I'm bronze 5 to start off with 130k Mastery Score on Varus. Level 6 on him. So, I had a pretty good game with my main champion. It was a 5v4. We were a person down. How do you higher elo players think I did? Any tips on my build? http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2223433862/230334968?tab=overview
