Front teeth flare out/protrude after getting my braces off? (photo)

I just got my braces off and my front teeth seem to slant out. Is this normal? Am I overreacting? Can this be fixed with my retainer or maybe invisaign (don't want to go back to braces)? I'm going to ask my orthodontist about it when i go see him tomorrow, so I just want a second opinion. By the way, I'm getting an implant done soon for the obvious tooth thats missing so I want to correct this (if it needs to be) before I do that.
