I talked a lot in my bird essay how my birds motivated me to pursue biology and how it spread to my interest with the human system. I talked about my devotion to study, including collecting feathers for analysis, buying textbooks, and filling sketchbooks with their anatomy and in different positions. I even mentioned how I am up to the challenge in combining bird and human anatomy in a way that is feasible. I think the essay is unconventional.
The other one is slightly more conventional, as it asks for a biographical review. It includes things about my job, my dad’s occupation and how I help him, etc. However I emphasized the uniqueness of my dad’s job in a way that may captivate a reader. I’m not sure, though.
