I enjoyed reading about your adventure. I'm so jealous, you got to swim with dolphines-that is so cool! Your essay is awesome and it includes many real accounts out in nature, that seem to have had a real impact on your life. You might just want to include what this vacation did for you. I know that it gave you the opportunity to enjoy nature but be more specific, tell how it impacted your life. Oh yes and you might want to add a quote, but it's just a suggestion. Other than that, Very nicely written.
