I would say that most likely your beer will be fine. You used a yeast strain that, even under high fermentation temperatures creates low esters. Even if you have elevated levels of esters, that's not always a bad thing. My only concern would be that your fermentation attenuated too quickly, which will lead to excessive formation of fusel alcohols (those nasty alcohols present in large amounts in red wine that give you a harsh buzz and even harsher hang over with a headache). Overall though, I think you are fine. Many Belgian brewers start their fermentations at 65F and just let it go. Duvel reports having fermentations as high as 93F, and they still make very good beer. You should be just fine. Enjoy your beer!
